Setting up C Development Environment The "Setting up C Development Environment" section in the "Introduction to C Programming" module of the book "C Programming: Building Blocks of Modern Code" serves as a practical guide for readers to establish a conducive environment for C programming. A well-configured development environment is crucial for efficient coding and testing. This section not only outlines the fundamental components required but also provides detailed steps for setting up a C development environment. Installing a C Compiler](https://image.slidesharecdn.com/27468065-250512224434-e1006567/75/C-Programming-Building-Blocks-Of-Modern-Code-Edet-Theophilus-22-2048.jpg)
![The first step in setting up a C development environment is installing a C compiler. The section details the process of installing a compiler like GCC (GNU Compiler Collection) on different operating systems, ensuring readers have a working compiler to translate their C code into executable programs. # Installing GCC on Linux sudo apt-get update sudo apt-get install build-essential Choosing an Integrated Development Environment (IDE) While a basic text editor can suffice for C programming, using a feature-rich IDE enhances the development experience. The module explores the benefits of using an IDE and guides readers in setting up Visual Studio Code (VS Code) for C development. # Installing VS Code on Ubuntu sudo snap install --classic code Configuring VS Code for C Programming Once VS Code is installed, the section provides step-by-step instructions for configuring the IDE to support C programming. This includes installing the C/C++ extension, setting up build tasks, and configuring debugging options. // .vscode/tasks.json { "version": "2.0.0", "tasks": [ { "label": "build", "type": "shell", "command": "gcc", "args": ["-g", "${file}", "-o", "${fileDirname}/${fileBasenameNoExtension}"] } ] } The above code snippet illustrates a simple build task in VS Code's tasks.json file, allowing users to compile their C code with the GCC compiler directly from the IDE. Adding Compiler Path to System Environment](https://image.slidesharecdn.com/27468065-250512224434-e1006567/75/C-Programming-Building-Blocks-Of-Modern-Code-Edet-Theophilus-23-2048.jpg)
![float height = 5.9; The char data type is reserved for single characters, while double is used for double-precision floating-point numbers. char grade = 'A'; double pi = 3.14159; Derived Data Types In addition to fundamental types, C supports derived data types like arrays, structures, and pointers. Arrays allow the grouping of elements under a single variable name, facilitating the storage of collections of data. int scores[5] = {85, 90, 78, 92, 88}; Here, an integer array scores is declared to hold five elements. The indices allow accessing individual values within the array. User-Defined Data Types C also enables the creation of user-defined data types through structures. Structures group multiple variables under a single name, enhancing code organization and readability. struct Point { int x; int y; }; struct Point p1 = {3, 7}; The code snippet defines a structure named Point with two members x and y. An instance p1 is then declared, representing a point in a Cartesian coordinate system. Pointers for Memory Management Pointers are a powerful feature in C, allowing direct manipulation of memory addresses. They enhance efficiency and flexibility but require careful handling to avoid memory-related issues. int num = 42; int *ptr = #](https://image.slidesharecdn.com/27468065-250512224434-e1006567/75/C-Programming-Building-Blocks-Of-Modern-Code-Edet-Theophilus-29-2048.jpg)
![Functions can take parameters, which are values passed to them, and return values, which are the results they produce. Understanding how to define and utilize these aspects is vital for creating versatile and effective functions. // Function with parameters and return value float calculateAverage(int array[], int size) { float sum = 0; for (int i = 0; i < size; ++i) { sum += array[i]; } return sum / size; } In this example, the calculateAverage function takes an array and its size as parameters, calculates the sum of its elements, and returns the average. Functions with parameters and return values enhance code reusability and flexibility. Recursive Functions C supports recursive functions, allowing a function to call itself. Recursive functions are often employed for solving problems that can be broken down into smaller, similar sub-problems. // Recursive function to calculate factorial int factorial(int n) { if (n == 0 || n == 1) { return 1; } else { return n * factorial(n - 1); } } In this instance, the factorial function calculates the factorial of a number using recursion. Recursive functions provide an elegant way to express complex algorithms. Variable Scope and Lifetime Understanding the scope and lifetime of variables within functions is crucial. Variables declared within a function are local to that function and have limited visibility outside of it. int globalVariable = 10; // Global variable](https://image.slidesharecdn.com/27468065-250512224434-e1006567/75/C-Programming-Building-Blocks-Of-Modern-Code-Edet-Theophilus-40-2048.jpg)
![Here, the squareByReference function takes a pointer to an integer and modifies the value at that memory address, affecting the original variable number in the main function. Return Values Functions in C can return values to the calling code, allowing them to communicate results or perform computations. The return type is specified in the function declaration and definition. // Function declaration with return type float calculateAverage(int array[], int size); // Function definition with return type float calculateAverage(int array[], int size) { float sum = 0; for (int i = 0; i < size; ++i) { sum += array[i]; } return sum / size; } In this example, the calculateAverage function returns the average of an array of numbers. The return type (float in this case) indicates the type of value the function will provide. Multiple Return Values C functions can only directly return a single value. However, multiple values can be effectively returned by using pointers or structures. // Function with multiple return values using pointers void getMinMax(int array[], int size, int *min, int *max) { // Logic to find min and max // Assign results to *min and *max } int main() { int numbers[] = {3, 7, 1, 9, 4}; int minValue, maxValue; getMinMax(numbers, 5, &minValue, &maxValue); // minValue and maxValue now contain the minimum and maximum values, respectively return 0; }](https://image.slidesharecdn.com/27468065-250512224434-e1006567/75/C-Programming-Building-Blocks-Of-Modern-Code-Edet-Theophilus-43-2048.jpg)
![knowledge of the function signatures, potentially leading to errors or unexpected behavior. // Function prototype int calculateProduct(int x, int y); int main() { int result = calculateProduct(3, 4); return 0; } // Function definition int calculateProduct(int x, int y) { return x * y; } In this example, the prototype informs the compiler about the calculateProduct function, allowing the main function to call it before its actual definition. Avoiding Implicit Int Function Declarations In older C standards, when a function was called without a prototype, the compiler implicitly assumed it returned an int. This could lead to subtle bugs if the function returned a different type. // No prototype double calculateAverage(int array[], int size); int main() { double result = calculateAverage(numbers, 5); return 0; } // Function definition double calculateAverage(int array[], int size) { // Logic to calculate average return sum / size; } Here, the absence of a prototype in the main function could lead to a mismatch if the compiler assumes calculateAverage returns an int. Utilizing function prototypes ensures proper type checking and eliminates this ambiguity. Default Arguments in Prototypes](https://image.slidesharecdn.com/27468065-250512224434-e1006567/75/C-Programming-Building-Blocks-Of-Modern-Code-Edet-Theophilus-45-2048.jpg)
![C does not support default function arguments like some other languages. However, function prototypes allow for a certain degree of flexibility by declaring functions with parameters that are not strictly enforced during the definition. // Function prototype with additional parameters int multiply(int a, int b, int c); In this case, the prototype introduces an additional parameter c that may not be present in the actual function definition. While this is not a true default argument, it provides a level of flexibility in function declarations. Header Files and Function Prototypes Function prototypes are commonly placed in header files (.h) in larger C projects. This practice centralizes declarations, making them accessible to multiple source files. // Example header file (calculate.h) #ifndef CALCULATE_H #define CALCULATE_H int calculateSum(int a, int b); double calculateAverage(int array[], int size); #endif By including this header file in source files that require these functions, the compiler gains knowledge of the function prototypes, promoting modular code design and ease of maintenance. Function prototypes are an integral part of C programming, providing a mechanism to declare functions before their actual implementation. This practice enhances code organization, improves readability, and prevents potential errors arising from implicit assumptions about function signatures. Understanding the significance of function prototypes is essential for writing clear, error-free, and maintainable C code.

This includes installing the C/C++ extension, setting up build tasks, and configuring debugging options. // .vscode/tasks.json { "version": "2.0.0", "tasks": [ { "label": "build", "type": "shell", "command": "gcc", "args": ["-g", "${file}", "-o", "${fileDirname}/${fileBasenameNoExtension}"] } ] } The above code snippet illustrates a simple build task in VS Code's tasks.json file, allowing users to compile their C code with the GCC compiler directly from the IDE. Adding Compiler Path to System Environment
- 24. To ensure seamlesscompilation from the command line, the section guides users in adding the compiler's path to the system environment variables. This step is crucial for enabling the execution of compiler commands from any directory in the terminal. # Adding GCC to the PATH on Linux export PATH=$PATH:/path/to/gcc The "Setting up C Development Environment" section not only emphasizes the importance of a well-configured environment but also provides hands-on guidance, making it accessible for readers to set up their C development environment using a powerful and popular IDE like Visual Studio Code. Basic Structure of a C Program The module "Introduction to C Programming" in the book "C Programming: Building Blocks of Modern Code" dives into the essential foundation of C programming by dissecting the basic structure of a C program. Understanding this structure is crucial for novices as it lays the groundwork for writing efficient and organized code. Include Directives A C program typically begins with include directives to bring in libraries and header files, essential for accessing predefined functions and features. For instance, the #include <stdio.h> directive includes the standard input/output library, allowing the use of functions like printf and scanf. #include <stdio.h> Main Function The heart of every C program is the main function. Execution starts from the main function, making it a mandatory component. The main function encapsulates the code that will be executed when the program runs. int main() { // Code inside the main function return 0;
- 25. } The int beforemain indicates that the function returns an integer value, conventionally used to convey the program's exit status. Variables and Data Types Following the main function, C programs often declare variables to store and manipulate data. C supports various data types such as int, float, and char. Declaring variables with specific data types helps in efficient memory allocation. int main() { int age = 25; float height = 5.9; char grade = 'A'; // Additional variable declarations and code return 0; } Statements and Control Flow C programs execute a series of statements within the main function. These statements can include assignments, mathematical operations, and conditional structures like if and else for control flow. int main() { int x = 10; if (x > 5) { printf("x is greater than 5n"); } else { printf("x is not greater than 5n"); } // Additional statements and code return 0; } Functions Beyond the main function, C programs can define additional functions to modularize code. Functions promote code reuse and maintainability. They consist of a return type, a function name, parameters, and the function body. int add(int a, int b) { return a + b;
- 26. } int main() { intresult = add(3, 7); printf("Sum: %dn", result); return 0; } The "Basic Structure of a C Program" section thus guides learners through the key components, enabling them to comprehend the anatomy of a C program and fostering a solid foundation for subsequent learning in the realm of C programming.
- 27. Module 2: Variables inC The Pillars of Data Storage and Manipulation In the module "Variables in C," readers embark on a pivotal exploration of one of the foundational elements that make C a powerhouse in programming. This chapter of "C Programming: Building Blocks of Modern Code" delves into the essence of variables, elucidating their role as the bedrock of data storage and manipulation within the C programming paradigm. Fundamentals of Variables: Storage Units for Data At its core, this module demystifies the concept of variables. Variables, in the C language, serve as dynamic containers capable of holding various data types. Readers will grasp the fundamental idea that, in C, variables act as storage units, allowing programmers to manipulate and work with different types of data efficiently. Data Types: Shaping the Character of Variables The module extends its focus to the diverse data types that variables can encapsulate. From integers and floating-point numbers to characters and pointers, the versatility of C becomes apparent. Each data type carries unique properties, influencing how data is stored, processed, and interpreted by the program. This nuanced understanding is critical for crafting efficient and precise C code. Variable Declaration and Initialization: Crafting the Blueprint An integral aspect of mastering variables in C involves the intricacies of declaration and initialization. This module delves into the syntax and
- 28. semantics of declaringvariables, emphasizing the importance of adhering to C's strict typing rules. Readers will grasp how the process of initialization sets the initial values of variables, laying the groundwork for a program's execution. Scope and Lifetime: Navigating the Temporal Landscape Beyond the basic concepts, the module ventures into the notions of scope and lifetime. These characteristics govern when and where variables exist within a program. From local variables confined to specific blocks of code to global variables with broader visibility, understanding the temporal landscape of variables is essential for writing robust and maintainable C programs. As readers progress through "Variables in C," they not only gain a profound understanding of the mechanics behind variables but also develop a foundational knowledge that will prove invaluable as they delve into more advanced programming concepts. This module serves as a cornerstone in building a solid comprehension of C programming, setting the stage for the mastery of subsequent building blocks in the world of modern code. Data Types and Declarations The "Variables in C" module within the book "C Programming: Building Blocks of Modern Code" delves into the critical aspect of data types and declarations, elucidating how they form the backbone of variable handling in C programming. Understanding data types is paramount for efficient memory utilization and ensuring accurate representation of information. Fundamental Data Types C provides several fundamental data types, each serving a specific purpose. The int data type, for instance, is commonly used for storing integer values. int age = 25; Here, the variable age is declared as an integer and assigned the value 25. Similarly, the float data type is employed for decimal or floating- point values.
- 29. float height =5.9; The char data type is reserved for single characters, while double is used for double-precision floating-point numbers. char grade = 'A'; double pi = 3.14159; Derived Data Types In addition to fundamental types, C supports derived data types like arrays, structures, and pointers. Arrays allow the grouping of elements under a single variable name, facilitating the storage of collections of data. int scores[5] = {85, 90, 78, 92, 88}; Here, an integer array scores is declared to hold five elements. The indices allow accessing individual values within the array. User-Defined Data Types C also enables the creation of user-defined data types through structures. Structures group multiple variables under a single name, enhancing code organization and readability. struct Point { int x; int y; }; struct Point p1 = {3, 7}; The code snippet defines a structure named Point with two members x and y. An instance p1 is then declared, representing a point in a Cartesian coordinate system. Pointers for Memory Management Pointers are a powerful feature in C, allowing direct manipulation of memory addresses. They enhance efficiency and flexibility but require careful handling to avoid memory-related issues. int num = 42; int *ptr = #
- 30. In this example,a pointer ptr is declared to store the address of the variable num. This provides a means to indirectly access and modify the value of num through the pointer. Type Modifiers C includes type modifiers to adjust the range and nature of data types. For instance, unsigned can be used to declare variables that only store positive values, effectively doubling the positive range of int. unsigned int positiveNumber = 100; The "Data Types and Declarations" section serves as a comprehensive guide within the "Variables in C" module, laying the groundwork for effective variable usage by exploring fundamental and derived data types, user-defined structures, pointers, and type modifiers. Understanding these concepts is pivotal for writing robust and efficient C programs. Memory Allocation The "Variables in C" module within the book "C Programming: Building Blocks of Modern Code" delves into the crucial concept of memory allocation. Understanding how memory is allocated and managed is essential for writing efficient and reliable C programs. This section illuminates the different aspects of memory allocation, from static allocation to dynamic allocation. Static Memory Allocation In C, memory can be statically allocated during compile-time. Variables declared with a fixed size are assigned memory when the program is compiled, and this memory remains constant throughout the program's execution. int count = 10; // Static memory allocation In this example, the variable count is statically allocated memory to store an integer value. The size of the memory is determined at compile-time and remains unchanged during program execution.
- 31. Dynamic Memory Allocation Dynamicmemory allocation, on the other hand, allows the program to request memory during runtime, providing flexibility for varying data requirements. The malloc function is commonly used for dynamic memory allocation. int *dynamicArray = (int *)malloc(5 * sizeof(int)); Here, malloc allocates memory for an array of five integers. The sizeof(int) ensures that the correct amount of memory is allocated based on the system's integer size. It's important to note that dynamically allocated memory needs to be explicitly deallocated using the free function to avoid memory leaks. free(dynamicArray); // Deallocating dynamically allocated memory Pointers and Memory Allocation Pointers play a pivotal role in memory allocation. They can be used to access dynamically allocated memory, providing a mechanism to manipulate memory locations directly. int *dynamicVariable = (int *)malloc(sizeof(int)); *dynamicVariable = 42; // Storing a value in dynamically allocated memory This example demonstrates dynamic memory allocation for a single integer. The pointer dynamicVariable holds the memory address, and the value 42 is stored at that location. Memory Allocation for Arrays and Structures Memory allocation extends to arrays and structures. When creating dynamic arrays or structures, careful memory management is essential to prevent memory leaks or undefined behavior. struct Point { int x; int y; }; struct Point *pointArray = (struct Point *)malloc(3 * sizeof(struct Point));
- 32. Here, dynamic memoryis allocated for an array of three Point structures. It's crucial to release this memory using free when it is no longer needed. Understanding memory allocation is fundamental to writing efficient and reliable C programs. The "Memory Allocation" section of the "Variables in C" module provides a comprehensive exploration of both static and dynamic memory allocation, empowering programmers to make informed decisions regarding memory usage in their C code. Constants and Literals The module on "Variables in C" within the book "C Programming: Building Blocks of Modern Code" explores the significant role of constants and literals in programming. Constants are fixed values that do not change during the execution of a program, while literals represent these constant values in a program's source code. Understanding how to use and declare constants and literals is essential for writing code that is both readable and maintainable. Numeric Constants Numeric constants represent fixed numerical values in a program. They can be integers, floating-point numbers, or even in scientific notation. For instance, an integer constant is declared as follows: const int MAX_COUNT = 100; In this example, MAX_COUNT is a constant holding the value 100, and the const keyword ensures that the value cannot be modified throughout the program's execution. Character and String Literals Character literals represent individual characters, enclosed within single quotes, and are used to assign values to char variables or constants. const char GRADE = 'A';
- 33. String literals, onthe other hand, are sequences of characters enclosed within double quotes. const char *welcomeMessage = "Hello, World!"; Here, welcomeMessage is a constant pointer to a string literal. The use of pointers in string literals allows for efficient manipulation and storage of character sequences. Symbolic Constants Symbolic constants are identifiers that represent constant values in a program. They are often defined using the #define preprocessor directive. #define PI 3.14159 This example declares a symbolic constant PI with the value 3.14159. Symbolic constants enhance code readability and maintainability by providing meaningful names for fixed values. Enumerations Enumerations, or enums, allow programmers to create named integer constants. They provide a way to represent a set of named integer values with more meaningful names. enum Days { MON, TUE, WED, THU, FRI, SAT, SUN }; Here, an enum named Days is declared, representing the days of the week with corresponding integer values. Enums enhance code clarity by replacing "magic numbers" with meaningful identifiers. Hexadecimal and Octal Literals C supports hexadecimal and octal literals for expressing values in base-16 and base-8, respectively. Hexadecimal literals are prefixed with '0x,' and octal literals are prefixed with '0.' int hexValue = 0x1A; // Hexadecimal literal int octalValue = 034; // Octal literal
- 34. Understanding how toutilize these numeric systems provides flexibility in representing values in different bases. The "Constants and Literals" section within the "Variables in C" module serves as a comprehensive guide, illustrating the various ways constants and literals are employed in C programming. A solid grasp of these concepts is pivotal for creating code that is not only robust but also easy to understand and maintain. Dynamic Memory Allocation The "Variables in C" module within the book "C Programming: Building Blocks of Modern Code" delves into the intricacies of dynamic memory allocation, a crucial aspect of C programming that allows for flexible memory management during runtime. Unlike static memory allocation, dynamic memory allocation enables programs to allocate and deallocate memory as needed, facilitating efficient memory usage and enhancing program flexibility. Using malloc() for Memory Allocation The primary function for dynamic memory allocation in C is malloc(). It stands for "memory allocation" and is used to request a specified number of bytes from the heap, returning a pointer to the beginning of the allocated memory. int *dynamicArray = (int *)malloc(5 * sizeof(int)); In this example, dynamicArray is a pointer to an integer that is dynamically allocated to store an array of five integers. The sizeof(int) ensures that the correct amount of memory is allocated based on the system's integer size. calloc() for Allocating and Initializing The calloc() function is another dynamic memory allocation function that not only allocates memory but also initializes all the allocated memory to zero. int *zeroedArray = (int *)calloc(8, sizeof(int));
- 35. Here, zeroedArray isa pointer to an array of eight integers, and all the elements are initialized to zero. This is particularly useful when a program requires a block of memory with specific initial values. realloc() for Resizing Memory Dynamic memory can be resized during runtime using the realloc() function. This function takes a pointer to a previously allocated memory block and adjusts its size. int *resizedArray = (int *)realloc(dynamicArray, 10 * sizeof(int)); In this example, dynamicArray is resized to accommodate ten integers. It's important to note that realloc() may return a different pointer if it needs to move the memory block, so it's essential to assign the result back to the original pointer. Deallocating Memory with free() To prevent memory leaks, it is crucial to deallocate dynamically allocated memory once it is no longer needed. The free() function is used for this purpose. free(dynamicArray); free(zeroedArray); free(resizedArray); This snippet demonstrates the proper use of free() to release the memory allocated for dynamicArray, zeroedArray, and resizedArray. Failing to free dynamically allocated memory can lead to memory leaks, impacting the program's performance. Error Handling and NULL Checks Dynamic memory allocation is susceptible to failure, especially when the system runs out of memory. It is good practice to check the return value of allocation functions for NULL to handle such situations gracefully. int *newArray = (int *)malloc(size * sizeof(int)); if (newArray == NULL) { printf("Memory allocation failed.n"); exit(EXIT_FAILURE);
- 36. } Here, the programchecks if the allocation was successful, and if not, it prints an error message and exits the program. The "Dynamic Memory Allocation" section provides a comprehensive guide within the "Variables in C" module, offering insights into the functions and practices related to allocating and managing memory dynamically in C programs. Understanding these concepts is fundamental for writing robust and memory-efficient C code.
- 37. Module 3: Functions inC Crafting Modular and Reusable Code The module "Functions in C" stands as a pivotal chapter in the narrative of "C Programming: Building Blocks of Modern Code." In the vast landscape of C programming, functions emerge as indispensable tools for structuring code, promoting reusability, and fostering modular design. This exploration unveils the intricacies of functions in C, elucidating their role as dynamic building blocks in the construction of robust and scalable programs. The Essence of Functions: Decomposing Complexity At its core, the module immerses readers in the essence of functions — self- contained units of code designed to perform specific tasks. This concept aligns seamlessly with C's commitment to procedural programming, allowing developers to decompose complex problems into manageable and comprehensible parts. Readers will delve into the syntax of function definition, understanding how to declare, implement, and invoke functions to streamline their code. Function Parameters: Bridging Data into the Function Realm A significant portion of the module unravels the concept of function parameters. Parameters act as bridges, enabling the passage of data into functions. The discussion spans the diverse types of parameters, including those that allow the function to receive input and others that facilitate the return of values. Readers gain insight into the nuances of parameter passing, appreciating how it contributes to the flexibility and adaptability of C functions. Return Values: Harvesting Results from Function Orchestrations
- 38. The narrative extendsto the crucial role of return values. Functions in C are not merely isolated operations; they are orchestrators that produce outcomes. The module elucidates the mechanisms of returning values from functions, emphasizing the importance of conveying results to the broader context of a program. This dynamic aspect of functions empowers developers to create efficient and purposeful code. Scope and Lifetime of Variables: Navigating the Function Landscape A deep dive into functions necessitates an understanding of the scope and lifetime of variables within their domain. This module unfurls the temporal landscape of variables, illuminating how local and global variables operate within the context of functions. Such comprehension is pivotal for crafting modular and maintainable code, ensuring that functions encapsulate their logic while interacting seamlessly with the broader program. As readers navigate the realms of "Functions in C," they not only grasp the syntax and mechanics of function implementation but also cultivate a mindset geared towards modular design and code reusability. This module serves as a catalyst for embracing the power of functions, setting the stage for the development of intricate and scalable C programs. Function Declaration and Definition The "Functions in C" module within the book "C Programming: Building Blocks of Modern Code" delves into the importance of function declaration and definition, a fundamental concept that enhances code modularity and reusability. In C, functions play a pivotal role in organizing code into manageable units, and understanding how to declare and define them is essential for creating structured and maintainable programs. Function Declaration A function declaration informs the compiler about the function's name, return type, and the types of its parameters. It serves as a prototype that allows the compiler to understand how to call the function and what values to expect. // Function declaration int add(int a, int b);
- 39. Here, the functionadd is declared with a return type of int and two integer parameters. The declaration enables other parts of the program to call the function without having the entire function definition available. Function Definition The function definition provides the actual implementation of the function, detailing the logic executed when the function is called. // Function definition int add(int a, int b) { return a + b; } In this example, the add function adds two integers and returns the result. The function definition includes the return type, function name, parameter types, and the actual code within curly braces. Function Prototypes Function prototypes are a form of forward declaration, allowing the compiler to recognize functions before their definitions appear in the code. They are particularly useful when functions are defined after they are called in the program. // Function prototype int multiply(int x, int y); int main() { int result = multiply(3, 4); return 0; } // Function definition int multiply(int x, int y) { return x * y; } Here, the prototype for the multiply function is declared at the beginning, enabling its use in the main function before its definition. Function Parameters and Return Values
- 40. Functions can takeparameters, which are values passed to them, and return values, which are the results they produce. Understanding how to define and utilize these aspects is vital for creating versatile and effective functions. // Function with parameters and return value float calculateAverage(int array[], int size) { float sum = 0; for (int i = 0; i < size; ++i) { sum += array[i]; } return sum / size; } In this example, the calculateAverage function takes an array and its size as parameters, calculates the sum of its elements, and returns the average. Functions with parameters and return values enhance code reusability and flexibility. Recursive Functions C supports recursive functions, allowing a function to call itself. Recursive functions are often employed for solving problems that can be broken down into smaller, similar sub-problems. // Recursive function to calculate factorial int factorial(int n) { if (n == 0 || n == 1) { return 1; } else { return n * factorial(n - 1); } } In this instance, the factorial function calculates the factorial of a number using recursion. Recursive functions provide an elegant way to express complex algorithms. Variable Scope and Lifetime Understanding the scope and lifetime of variables within functions is crucial. Variables declared within a function are local to that function and have limited visibility outside of it. int globalVariable = 10; // Global variable
- 41. void modifyGlobalVariable() { globalVariable= 20; // Modifying the global variable } int main() { modifyGlobalVariable(); // globalVariable is now 20 return 0; } In this example, the modifyGlobalVariable function can access and modify the global variable, but local variables within functions are confined to their respective scopes. The "Function Declaration and Definition" section of the "Functions in C" module provides a comprehensive exploration of the foundational concepts related to creating and utilizing functions in C programming. Mastery of these concepts is essential for writing modular, readable, and maintainable code in the C language. Parameters and Return Values The "Functions in C" module within the book "C Programming: Building Blocks of Modern Code" extensively covers the crucial aspects of parameters and return values, essential components for creating versatile and reusable functions in C. Understanding how to define, pass, and utilize parameters, as well as how to manage return values, is fundamental for effective function implementation. Function Parameters Function parameters enable the passing of values to a function, allowing it to operate on specific data. Parameters are specified within the function declaration and definition, defining the type and name of each parameter. // Function declaration with parameters int add(int a, int b); // Function definition with parameters int add(int a, int b) { return a + b; }
- 42. In this example,the add function takes two parameters, a and b, and returns their sum. Parameters enhance the flexibility and reusability of functions, as they allow the function to work with different input values. Passing Parameters by Value By default, C uses a "pass-by-value" mechanism when passing parameters to functions. This means that the actual values of the arguments are copied into the function parameters, preserving the original values outside the function. void square(int x) { x = x * x; // Changes only the local copy of x } int main() { int number = 5; square(number); // 'number' remains 5 after the function call return 0; } In this case, the square function attempts to modify the parameter x, but the original value of number in the main function remains unchanged. Passing Parameters by Reference While C primarily uses pass-by-value, it is possible to achieve pass- by-reference-like behavior by passing the address of a variable (a pointer) to a function. This allows the function to directly manipulate the value stored at that memory address. void squareByReference(int *x) { *x = (*x) * (*x); // Modifies the value at the memory address pointed to by x } int main() { int number = 5; squareByReference(&number); // 'number' is now 25 after the function call return 0; }
- 43. Here, the squareByReferencefunction takes a pointer to an integer and modifies the value at that memory address, affecting the original variable number in the main function. Return Values Functions in C can return values to the calling code, allowing them to communicate results or perform computations. The return type is specified in the function declaration and definition. // Function declaration with return type float calculateAverage(int array[], int size); // Function definition with return type float calculateAverage(int array[], int size) { float sum = 0; for (int i = 0; i < size; ++i) { sum += array[i]; } return sum / size; } In this example, the calculateAverage function returns the average of an array of numbers. The return type (float in this case) indicates the type of value the function will provide. Multiple Return Values C functions can only directly return a single value. However, multiple values can be effectively returned by using pointers or structures. // Function with multiple return values using pointers void getMinMax(int array[], int size, int *min, int *max) { // Logic to find min and max // Assign results to *min and *max } int main() { int numbers[] = {3, 7, 1, 9, 4}; int minValue, maxValue; getMinMax(numbers, 5, &minValue, &maxValue); // minValue and maxValue now contain the minimum and maximum values, respectively return 0; }
- 44. Here, the getMinMaxfunction takes an array, its size, and two pointers (min and max) to store the minimum and maximum values. The function modifies the values indirectly through the pointers. Understanding parameters and return values is fundamental for harnessing the full potential of functions in C. The ability to pass data into functions and receive results back enhances the modularity and clarity of code, facilitating the creation of robust and reusable software. Function Prototypes The module on "Functions in C" within the book "C Programming: Building Blocks of Modern Code" introduces the concept of function prototypes, a vital aspect of C programming that enhances code organization and allows for better modularity. Function prototypes serve as declarations that inform the compiler about the existence and signature of a function before its actual implementation, enabling smooth integration and avoiding potential issues related to function calls. Introduction to Function Prototypes In C, a function prototype provides the compiler with information about a function's name, return type, and parameters. This enables the compiler to validate function calls and ensure their correctness before the actual function definitions are encountered. // Function prototype int calculateSum(int a, int b); Here, the function prototype for calculateSum declares that the function takes two integers as parameters (a and b) and returns an integer. This declaration allows the compiler to understand how the function should be used even before its definition. Benefits of Function Prototypes The primary advantage of function prototypes is evident when functions are defined after they are called in the program. Without prototypes, the compiler might encounter function calls without prior
- 45. knowledge of thefunction signatures, potentially leading to errors or unexpected behavior. // Function prototype int calculateProduct(int x, int y); int main() { int result = calculateProduct(3, 4); return 0; } // Function definition int calculateProduct(int x, int y) { return x * y; } In this example, the prototype informs the compiler about the calculateProduct function, allowing the main function to call it before its actual definition. Avoiding Implicit Int Function Declarations In older C standards, when a function was called without a prototype, the compiler implicitly assumed it returned an int. This could lead to subtle bugs if the function returned a different type. // No prototype double calculateAverage(int array[], int size); int main() { double result = calculateAverage(numbers, 5); return 0; } // Function definition double calculateAverage(int array[], int size) { // Logic to calculate average return sum / size; } Here, the absence of a prototype in the main function could lead to a mismatch if the compiler assumes calculateAverage returns an int. Utilizing function prototypes ensures proper type checking and eliminates this ambiguity. Default Arguments in Prototypes
- 46. C does notsupport default function arguments like some other languages. However, function prototypes allow for a certain degree of flexibility by declaring functions with parameters that are not strictly enforced during the definition. // Function prototype with additional parameters int multiply(int a, int b, int c); In this case, the prototype introduces an additional parameter c that may not be present in the actual function definition. While this is not a true default argument, it provides a level of flexibility in function declarations. Header Files and Function Prototypes Function prototypes are commonly placed in header files (.h) in larger C projects. This practice centralizes declarations, making them accessible to multiple source files. // Example header file (calculate.h) #ifndef CALCULATE_H #define CALCULATE_H int calculateSum(int a, int b); double calculateAverage(int array[], int size); #endif By including this header file in source files that require these functions, the compiler gains knowledge of the function prototypes, promoting modular code design and ease of maintenance. Function prototypes are an integral part of C programming, providing a mechanism to declare functions before their actual implementation. This practice enhances code organization, improves readability, and prevents potential errors arising from implicit assumptions about function signatures. Understanding the significance of function prototypes is essential for writing clear, error-free, and maintainable C code. Recursion in C The module on "Functions in C" within the book "C Programming: Building Blocks of Modern Code" explores the powerful concept of
- 47. recursion. Recursion isa programming technique where a function calls itself, allowing for the repetition of a particular set of operations. This section delves into the principles of recursion in C, its applications, and considerations for effective implementation. Understanding Recursion Recursion simplifies complex problems by breaking them down into smaller, more manageable sub-problems. The base case, a condition where the function does not call itself, is crucial for preventing an infinite loop. Each recursive call tackles a smaller part of the problem, gradually converging towards the base case. // Recursive function to calculate factorial int factorial(int n) { if (n == 0 || n == 1) { return 1; // Base case } else { return n * factorial(n - 1); // Recursive call } } In this example, the factorial function calculates the factorial of a number using recursion. The base case ensures the recursion stops when n reaches 0 or 1. Recursive vs. Iterative Approaches Recursion is often an elegant and intuitive solution, but it may not always be the most efficient. Some problems are better suited for iterative approaches using loops. The choice between recursion and iteration depends on the nature of the problem and performance considerations. // Iterative approach to calculate factorial int factorialIterative(int n) { int result = 1; for (int i = 1; i <= n; ++i) { result *= i; } return result; }
- 48. This iterative versionof calculating factorial achieves the same result as the recursive approach. While recursion can lead to more readable code in certain scenarios, iterative solutions may offer better performance. Memory Usage in Recursion Recursive functions utilize the call stack to manage multiple function calls. Each recursive call adds a new frame to the stack, consuming memory. Excessive recursion without proper termination conditions can lead to a stack overflow, causing program termination. // Recursive function to calculate Fibonacci sequence int fibonacci(int n) { if (n <= 1) { return n; // Base case } else { return fibonacci(n - 1) + fibonacci(n - 2); // Recursive call } } In the fibonacci function, each recursive call contributes to the call stack. While recursion is elegant for expressing Fibonacci calculations, it becomes inefficient for large values of n due to redundant computations. Tail Recursion and Optimization Tail recursion is a special case where the recursive call is the last operation in the function. Some compilers can optimize tail-recursive functions to use constant stack space, avoiding stack overflow issues. // Tail-recursive function int factorialTailRecursive(int n, int accumulator) { if (n == 0) { return accumulator; // Base case } else { return factorialTailRecursive(n - 1, n * accumulator); // Tail-recursive call } } The factorialTailRecursive function is tail-recursive, allowing for potential optimization by certain compilers.
- 49. Proper Handling ofRecursive Cases When designing recursive functions, it's crucial to ensure that the recursive calls lead towards the base case. Failing to do so may result in infinite recursion, consuming excessive stack space and leading to program termination. // Incorrect recursive function without reaching base case void infiniteRecursion(int n) { printf("%dn", n); infiniteRecursion(n + 1); // Recursive call without approaching a base case } This example demonstrates an incorrect recursive function that lacks a proper termination condition, leading to an infinite loop. Recursion is a powerful and versatile technique in C programming that simplifies complex problems by breaking them down into more manageable sub-problems. Properly designed recursive functions enhance code readability and maintainability, but careful consideration must be given to base cases, termination conditions, and potential performance implications. Understanding the principles of recursion empowers programmers to approach problem-solving with a fresh and elegant perspective.
- 50. Module 4: Conditions andDecision Making Navigating Program Flow The module "Conditions and Decision Making" within the book "C Programming: Building Blocks of Modern Code" is a pivotal exploration into the realm of program control. In the intricate tapestry of C programming, the ability to make decisions dynamically based on certain conditions is a cornerstone skill. This module unveils the syntax, concepts, and nuances of decision-making structures in C, empowering programmers to sculpt code that adapts intelligently to diverse scenarios. Foundations of Decision Making: The 'if' and 'else' Constructs At its core, the module immerses readers in the foundational constructs of decision making — the 'if' and 'else' statements. These building blocks enable programmers to introduce conditional logic into their code, allowing the execution of different branches based on the evaluation of specified conditions. Readers will gain a comprehensive understanding of the syntax and applications of these constructs, laying the groundwork for more intricate decision-making scenarios. Extended Decision-Making: The 'switch' Statement The exploration extends to the versatile 'switch' statement, providing an alternative approach to decision making. Unlike the 'if' and 'else' constructs, the 'switch' statement allows for multi-branch decision making based on the value of an expression. This section of the module delves into the syntax and applications of the 'switch' statement, offering insights into when to leverage its capabilities for cleaner and more concise code. Logical Operators: Crafting Complex Conditions
- 51. A significant portionof the module delves into the world of logical operators. These operators — '&&' (logical AND), '||' (logical OR), and '!' (logical NOT) — serve as tools for crafting intricate conditions that respond to multiple criteria. Readers will grasp the art of combining conditions, creating decision-making structures that reflect the complexity of real- world scenarios. Nested Decision Making: Crafting Hierarchical Logic The narrative expands to the concept of nested decision making, where conditions are layered within one another. This advanced technique enables programmers to create hierarchical logic, where the fulfillment of one condition triggers the evaluation of another. Readers will master the art of crafting nested 'if' statements, unlocking the potential to address intricate decision-making scenarios with precision and clarity. As readers progress through "Conditions and Decision Making," they not only acquire the technical proficiency to implement decision-making structures but also cultivate a strategic approach to crafting code that responds intelligently to varying conditions. This module serves as a gateway to the dynamic world of program control in C, paving the way for the development of resilient and adaptive programs. if, else if, else Statements The "Conditions and Decision Making" module within the book "C Programming: Building Blocks of Modern Code" introduces the fundamental concept of decision-making in C through the if, else if, and else statements. These control structures allow programmers to execute specific blocks of code based on the evaluation of conditions, enabling the creation of flexible and responsive programs. The if Statement The if statement is the cornerstone of decision-making in C. It allows the execution of a block of code only if a specified condition is true. int num = 10; if (num > 0) { printf("The number is positive.n"); }
- 52. In this example,the printf statement will only be executed if the condition num > 0 is true. If the condition is false, the code block will be skipped. The else if Statement The else if statement provides a way to test multiple conditions sequentially. If the preceding if condition is false, the else if statement allows the evaluation of an additional condition. int num = 0; if (num > 0) { printf("The number is positive.n"); } else if (num < 0) { printf("The number is negative.n"); } else { printf("The number is zero.n"); } In this scenario, the program checks multiple conditions using else if. If none of the conditions is true, the else block is executed, providing a default case. The else Statement The else statement provides a fallback option when none of the preceding conditions are true. It allows the execution of a default block of code. int num = -5; if (num > 0) { printf("The number is positive.n"); } else { printf("The number is non-positive.n"); } Here, if the condition num > 0 is false, the else block will be executed, printing that the number is non-positive. Nested if Statements Conditional statements can be nested, allowing for more complex decision-making scenarios. Nested if statements are useful when
- 53. multiple conditions needto be evaluated based on the outcome of outer conditions. int num = 10; if (num > 0) { if (num % 2 == 0) { printf("The number is positive and even.n"); } else { printf("The number is positive and odd.n"); } } else { printf("The number is non-positive.n"); } In this example, the inner if statement checks whether the positive number is even or odd, depending on the outcome of the outer if condition. Common Mistakes and Best Practices When working with if, else if, and else statements, it's crucial to avoid common mistakes, such as missing braces for code blocks or failing to account for all possible scenarios. Additionally, maintaining code readability by properly indenting nested statements enhances code comprehension. int num = 42; // Incorrect indentation if (num > 0) { printf("The number is positive.n"); } else { printf("The number is non-positive.n"); } This snippet highlights the importance of consistent indentation for clear code presentation. Ternary Operator as a Compact Alternative The ternary operator (? :) provides a concise alternative for simple conditional expressions, especially when assigning values based on a condition. int num = 7;
- 54. printf("The number is%s.n", (num % 2 == 0) ? "even" : "odd"); In this example, the ternary operator is used to determine whether the number is even or odd within a single line, showcasing a more compact syntax. The "if, else if, else Statements" section within the "Conditions and Decision Making" module serves as a foundation for understanding how C programs make decisions based on different conditions. Proper usage of these statements enables programmers to create dynamic and responsive code that can adapt to various scenarios. Switch-Case Statements The "Conditions and Decision Making" module in the book "C Programming: Building Blocks of Modern Code" introduces the switch-case statements, a powerful control structure designed to simplify decision-making processes involving multiple possible conditions. The switch-case construct provides an organized and efficient way to handle various cases, offering an alternative to cascading if-else if statements. Introduction to Switch-Case The switch-case structure is particularly useful when a program needs to compare a variable or expression against multiple constant values and execute different blocks of code based on the match. It improves code readability and maintainability by avoiding the need for extensive nested if-else constructs. int dayOfWeek = 3; switch (dayOfWeek) { case 1: printf("Mondayn"); break; case 2: printf("Tuesdayn"); break; case 3: printf("Wednesdayn"); break; // Additional cases for other days default:

DEAR HENRY,—Mr. Paulding and Miss Sedgewick, are, in my opinion, inferior in genius to the American writers I mentioned in my last. They may be classed as the secondary novelists of this country, though in general literature, Paulding is equal if not superior to Cooper. His tales are usually short and want interest; but his characters are well sketched, his incidents natural, and his opinions and observations characterized by good sense. There is, however, an affectation of humor in what he writes, that does not please me. It seems to consist more in the employment of quaint terms and odd phrases, than in the incident or character itself, and would appear to be the result of an early and frequent perusal of the works of Swift and Rabelais. His productions are neat and sensible, but not very imaginative or striking. The interest or curiosity of the reader is never powerfully excited, but he never fails to please by the manner in which he conducts his plots; the easy and perspicuous style he employs, the clear and happy illustration of the vice or folly he holds up to indignation or scorn, and the successful though sometimes exaggerated developement of the character he wishes to portray. In both Paulding and Cooper there is an overwhelming American feeling, which bursts forth on all occasions, and which, to a foreigner, seems to partake of the nature of deep rooted prejudice.
- 57. It results, however,I have no doubt, from an ardent love of country, increased perhaps by the silly contumelies and sarcasms of the reviewers and travellers of our country. Mr. Paulding has not displayed any great depth or expansion of mind in anything he has yet written, though he has tried his wing in both prose and verse. His forte is satire, which, like that of Horace, is more playful than mordant and bitter. The productions of Miss Sedgewick which I have seen, are remarkable for good sense, but without much vigor of imagination. She succeeds best in quiet life. The delineation of the workings of passion, and of stormy and powerful emotions, are beyond the reach of her powers; but what she attempts she always does well. Her plots are generally without complication, and display no great fertility of invention; the incidents are not very striking and the characters are sometimes tame, and occasionally extravagant. They are not like the delineations of Miss Edgeworth, or Miss Mitford. You cannot form an idea of the nationality of the individual she sketches, and would as soon take him for a native of any other country as of her own. There is a manifest defect in this particular, in all the novelists I have mentioned. With the exception of the Indians who are occasionally introduced, there is scarcely any difference between their Americans, and the inhabitants of other lands. Cooper has indeed presented a finer gallery of American characters than any other writer, especially in his sketches of the early settlers or pioneers; but his characters, except in a few instances, are not usually distinguished by striking national peculiarities. This may possibly originate from the singular fact that in this country where men are free to rove where inclination leads, and to be under no other restraint than that which religion, law, or decency imposes, there is less peculiarity of character or individuality, than in any other portion of the globe with which I am acquainted. They have not yet attempted to give as in England, sketches of American society as it now exists, or may have existed since the organization of their government. Whether such pictures would indeed be interesting I am not prepared to say; but from the society in which I have mingled, I do not think it has variety enough, or differs sufficiently from that of other civilized nations to render such pictures striking or
- 58. amusing. Genius, however,can accomplish every thing, and might give to what appears to be vapid and ennuyant, some novelty and interest. There are some other novelists in the United States, whose productions, as they have sunk, or are rapidly sinking into oblivion, it is scarcely necessary to name. One of these is a man of talent, who, you will recollect, was an occasional contributor to the literary periodicals of our country, while a resident there. I mean J. Neale. His romances, from their wildness and extravagance, have been but little read, and are now nearly forgotten. He still, however, employs his pen, I understand, in doing what he can to edify and amuse his countrymen. Novel reading has been legitimatized by Sir Walter Scott, and though his productions furnish an admirable standard, nothing in the nature of romance now goes amiss, and the demand for works of fancy seems to increase in proportion to the number issued from the press, and the food that is furnished. Although the Americans are great novel readers, there is not much of romance in their character. There is too much matter-of-fact about them; they are too calculating and money-making to serve the purposes of the novelist. They form but indifferent heroes and heroines of romance, and hence Cooper is obliged to resort to the sea to rake up pirates and smugglers, or to go back to the revolution or the early settlement of his country to find characters and incidents calculated to give verisimilitude and interest to his tales. In dramatic literature, but little has yet been done in the United States. Few appear to have devoted much of their attention to dramatic composition. I have seen but ten or twelve American plays in the course of my researches; and these, though they possessed a good deal of merit, have been suffered to sink into neglect, and are rarely performed. A much larger number, however, would appear to have been written and prepared for the stage. According to a catalogue I have lately seen, no less than 270 dramatic pieces have either been prepared for the theatre of this country, or written by Americans. Of these many were of course got up for temporary
- 59. purposes, and whenthese purposes were answered were no longer remembered; but you will be surprised to learn that of this number, commencing in 1775, there are no less than thirty-three tragedies, the best of which are those which have been recently brought out, Metamora, Ouralasqui, a prize tragedy by a lady of Kentucky, and a combination of tragedies, by Paine, called Brutus, which has been on the stage for several years. The rest are scarcely remembered. The writer who seems to have devoted the largest portion of his time to dramatic literature in this country and who may be called the father of the American drama, is Mr. Dunlap, who has figured for many years in the various characters of dramatist, manager, and painter. His dramatic pieces amount to about 50, and he has already outlived their fame. Some of his translations from the German are still exhibited; but his original compositions are now never performed, and are almost forgotten. Mr. J. N. Barker of Philadelphia, stands next in point of fecundity, having given birth to ten dramatic bantlings in the course of his life, some of which are very creditable to their parent, but none are, I believe, stock plays. The prejudice against native writers was at one time so strong that the managers deemed it prudent to announce Mr. Barker's Marmion, Sir Walter's poem dramatized, as the production of Thomas Morton the author of Columbus. Mr. Dunlap was also I understand obliged to resort to the same expedient in relation to two or three of his plays; but as moon as it was known, their popularity, which had at first been considerable, immediately ceased, and they were laid upon the shelf. Such are some of the difficulties with which the American writer has to struggle; but these I am happy to learn are now giving way, and a more liberal spirit is beginning to prevail. It is to be hoped that the dramatic muse of America will soon be enabled to triumph over all the impediments which she has had to encounter, and repose in the same bower and be crowned with the same chaplet as her more fortunate sister of romance. Among the American plays which accident brought under my notice, was a comedy in five acts, entitled the "Child of Feeling," published in 1809, and written by a citizen of Washington. It seems to have been a juvenile production, written without much knowledge of the world, but with a due regard
- 60. to the unities.The dialogue wants sprightliness and the plot interest, and I merely mention it now because its contains among its dramatis personæ a character which is to me entirely original, and which if he really existed, the author must I think have caricatured in his copy. He is called Etymology, and does not belie his name, for he is constantly occupied in tracing every word that is spoken by himself or others to its root, and makes as may easily be supposed, some comic and ludicrous blunders. Till very recently, the author of even a successful play received scarcely any compensation for his labor, and the fame he acquired was but of short duration. Now however, it is otherwise, and both reputation and emolument attend the successful dramatist. The comedies, by American writers that I have seen, are not remarkable for their wit or humor, and therefore do not long retain their hold upon the stage. Dramatic exhibitions are not however held by the Americans in very high estimation, and this may be one of the causes of the low state of dramatic literature here. But the principal causes would appear to be the want of leisure, the devotion of the people to higher and more lucrative avocations, and the facility with which dramatic productions of established merit and popularity can be obtained from England. These causes operate in like manner I conceive, to prevent the attainment of that high poetical excellence which has yet to be reached by the worshippers of the muse in this country. The following remarks on this subject by an American writer are so pertinent, that I will transcribe them for your information. "We regret to say," says he, speaking of American poetry, "that much less has been done than might reasonably have been expected, even during our short political existence. We have indeed as yet scarcely done anything at which an American can look with conscious pride, as a trophy of native poetic genius. The ponderous and vapid Epic of Barlow, and the still more leaden and senseless heroics of Emmons, are far from giving reputation to the poetry of our country; and the fugitive and occasional pieces of Percival, Bryant, Halleck, &c. are not exactly such as we should select as a proof that we have done much in poetry. We have been in existence as a nation for upwards of half a century, and yet we have produced nothing that is certain
- 61. to reach posterity,or that can be classed higher than the minor productions of Moore, Campbell, or Byron, of the present day. There is an apparent want of originality, and too great an appearance of imitation in the poetical efforts of our native bards to carry them far down the stream of time, though it must be conceded that they have discovered in these efforts no ordinary portion of genius. There would seem to be something either in the nature of our political institutions, or in the general character of our pursuits, which is inimical to the developement of high poetical power. We are not a very imaginative people; we prefer the reality to the ideal; we pursue the substance rather than the shadow. Our ambition is early fired by political distinction, or our exertions are directed to the attainment of competency or wealth. The public mind has been led into a train of thinking somewhat adverse to the indulgence of poetical enthusiasm, and not calculated to render it susceptible of deep and intense delight from the contemplation of poetical beauty. It has been led to consider that the highest efforts of genius are those which are displayed at the bar or in the senate, and to regard the power of forensic and parliamentary eloquence as the loftiest exhibition of intellectual excellence. To that which the mind is early taught to respect and admire its greatest exertions will be directed, and hence the number of those who resort to the profession of law, the career of legislation, or the pursuits of commerce," &c. It is unquestionably true, that no great original poetical work of distinguished merit has yet made its appearance in the United States, but it cannot at the same time be denied, that the individuals this writer has named, with Bryant, Sigourney, Willis, and several others, possess a fine poetical vein, the mens divinior of Horace. Some of their effusions contain passages of great beauty and splendor, and may be fairly classed with those of the first poets of our country. Most of them however, have merely what Mad. De Genlis calls the "art of making verses;" and either from the want of encouragement, the stimulus of praise, or continued enthusiasm, wing their flight briefly into the regions of poetic fancy, and seldom afterwards attempt any more lofty or daring excursions. But I must
- 62. pause. I willendeavor in my next to bring my remarks on the science and literature of the United States to a close. FINE PASSAGE IN HOOKER.

J. M. C. D. For the Southern Literary Messenger. GRAYSON GRIFFITH. There is in a pleasant part of the Old Dominion, a thrifty village named Goodcheer. The inhabitants, from the first settlement of the place, were kind, and bland, and social. Indeed many of them went further. They jested, they fiddled, they danced, they sang songs, they played at cards, they drank wine, they frolicked. Yet was there among them a strong and steady current of public opinion against acts of very low and gross meanness or depravity. They were not liars, or thieves, or swindlers, or rakes. In this village lived Gregory Griffith, the tanner, whose industry and probity earned for him a respectability and an independence rivalled by none except the old patriarch of the village, more generally known by the name of the Major. Gregory had married the eldest daughter of old farmer Ryefield, a woman well suited to make him happy. Her disposition was easy, and her habits industrious and economical. They were a bonny couple. "The day moved swiftly o'er their heads, Made up of innocence and love."
- 66. Fourteen months aftertheir marriage, their first born son, a lovely child, smiled in the face of his parents. Him they called Grayson. Nor was he the only pledge of their love. They alternately rejoiced over a daughter and a son, until their quiver was full, having four sons and three lovely daughters. The death of their second child, who bore her mother's name, had in the fourth year of their marriage, wrung the bleeding hearts of these parents, and chastened their feelings to sober thinking. Between their first born and their third child lay an interval of nearly five years—a period which Mr. and Mrs. Griffith always spoke of with deep emotion. Grayson, in his childhood, had but feeble health—a circumstance which secured to him very indulgent treatment. This indulgence rose to excess after the death of the lovely Martha, his little sister. So soon after the death of the daughter, as the gay villagers could with propriety, they planned a general meeting at Mr. Griffith's. They came, and after some time spent in sober enjoyment, a game of whist was proposed. The proposal sensibly affected Mrs. Griffith. She seemed to feel that it was too soon after her babe's death. The tears started in her eyes, and she sought a place to weep. She went to her toilet and bathed her face, and returned with an air of constrained cheerfulness. Meanwhile Mr. Griffith had taken his seat with a second company who were playing loo. Before Martha's death, Grayson had been regularly carried to the nursery, as the sun threw his lowest and latest beams on the summit of a hill in sight from the portico. But after the death of his sister, he was encouraged to spend the evening with his parents; and when overcome by sleep, his cradle and his pillow were the bosom and the lap of parental fondness. And when company was present, he was often awake until a late hour. On this evening every one had something to say to Master Grayson. All the ladies kissed him, and more than one promised him a daughter for a little sweetheart. When whist and loo became the amusement, Grayson was much interested, especially when he saw his father dealing out. The very beaminess of his eye seemed to throw a charm around the figures on every card. At first he said nothing. At last he went to his mother
- 67. and said: "Mamma,won't you teach me to do like papa? O, I wish sister Martha was not dead, that she might see the pretties papa has got. Mamma, what are the papers with the hearts on?" The mention of Martha's name overcame Mrs. Griffith. She led Grayson to her bed-room, and wept and kissed him until, overcome by sleep, he forgot his joys and his sorrows until the next day. The nurse having lodged the sweet boy in the long crib at the side of his parent's bed, Mrs. Griffith returned to her company. Either her appearance, or a sense of propriety in her guests, operated a speedy dissolution of the party. The company being gone, Mr. Griffith said he wished he had not consented to play that evening—that Martha had been dead but a year, and that he really thought that as his child had been taken to heaven when not two years old, it was time for him to begin to think of preparing to meet her. Mrs. Griffith wept at the mention of Martha's name, repeated what Grayson had said, observed that she had felt badly, but that they must not be melancholy. She also said it was very kind in the neighbors to endeavor to cheer them up. It was after midnight, in the month of June, before these parents slept at all. At the very dawn of day Grayson awoke his parents by kissing them often, and calling their names aloud. So soon as he could get his father's attention, he said: "O father, what were those pretty things you had in your hand last night? Father, were they yours? May I have some? Can't I do as you did with them? Father, what was you doing? Please, sir, give me some to carry to school to-day." Mr. Griffith was not displeased that Grayson did not wait for an answer to his interrogatories. To his request for some to carry to school, he replied that Mr. Birch, the teacher, was a religious man, and would not let the boys carry such things to school. Grayson said: "And an't you religious too, papa?" and kissed him. Mr. Griffith looked at his wife. They both smiled confusedly. After breakfast, some of the neighbors called and inquired for the welfare of the family. Some of the ladies kissed Grayson, as did his mother, and he went to school. At play-time he told the children what he had seen, and one of the older boys explained the matter to
- 68. the rest ofthe company. He said the old people loved fun, and also played for money—and yet they would not let their boys play. "Never mind," continued he, "I can make fun, if you will all beg some pins and bring here to-morrow. Now, fellows, don't forget—bring a good many." The next morning every mother and sister were faithfully plied for pins, and every boy's sleeve was brightened with them. Before the teacher had arrived, the elder boy, before named, had taught all his juniors two ways of playing pins—one on a hat, and the other called "heads or points." In a few days one boy had secured all the pins, and kept them safely in a little case made of a section of reed. The spirit of gambling, however, did not expire with the loss of the pins. Indeed the loss of the many was the gain of one, and that one was the object of profound admiration. In a day or two, one of the boys came to school with an ear of white and another of red corn, and a piece of chalk in his pocket, and whispered to all his play fellows that now they would have fine fun. Every urchin was restless for play-time. Grayson Griffith was sure the master's watch must have stopped or must be too slow, and said so. At length the hour of recreation came, and as soon as all were fairly out of the teacher's hearing, the aforesaid boy prepared to teach his fellows the game of fox and geese. With his chalk he chequered a board, and arranged his white and red grains in proper order— calling the white grains of corn geese, and the red foxes. Soon he initiated every boy, and Grayson Griffith among the number, in the mysteries of the game. Ere long it was proposed that every boy should ask for a cent at home, and bring it to school. It was done. Grayson Griffith asked for one cent, and his father gave him two, and his mother one. They said he was old enough to have pocket money. He was now nearly eight years old. In the playtime, all the boys agreed to throw heads or tails, until they had won or lost the money that could be had. At the end of the sport, Grayson had seven cents—but on his way home, he dropped one in the grass, and by throwing heads or tails
- 69. with another boy,he lost three more—so that at night he had no more and no less than in the morning. That evening he asked if his father would go to the race next day. His father replied he did not know. "Well," said Grayson, "I bet you three cents and my barlow knife against ninepence, that Colonel Riley's Firefly will beat General Hobson's young Medley." "You will bet?" said Mr. Griffith. "Why, yes," said Grayson, "did not you bet at loo, father?" Grayson and his father, as by mutual consent, waived the conversation. Next day Grayson told at school what had occurred. Mr. Griffith did not go to the races; but in the evening some of the gentlemen came to see him, and induced him to bet as high as twenty dollars on a game at loo. Grayson seemed hardly to notice the occurrence, yet he was in reality closely observing, and caught several of the expressions of the gentlemen visiters. The next day, at a game of fox and geese, he cried "Damme soul." And as he went to school he kept saying, "Clubs are trumps—high, low, jack and the game." He thought it sounded pretty. In the meantime Mr. Griffith's family increased. He had now three sons and a daughter; and Grayson would often promise to show his little brother how to play fox and geese when he should grow a little larger. Mrs. Griffith had also played at cards when any very special company was present, or she was much urged. Mr. Griffith about this time gave a hundred dollars towards building a church in the village, and subscribed twenty dollars a year towards the minister's salary; and many of the people had become very serious, and even religious. The good minister, like his master Jesus Christ, was very fond of children. All the children knew him in six weeks after he went to live in Goodcheer, and they all loved him. They would speak to him all the way across the street. One day Mr. Goodnews (for that was the minister's name) called at Mr. Griffith's, and asked Grayson if he knew how many commandments there
- 70. were. His answerwas, "I bet you I do." "But," said Mr. Goodnews, "I never bet, my dear little boy. Did not you know it was wrong to bet?" "No," said Grayson, "it is'nt—Father and mother bet." Mrs. Griffith's face colored, and she stammered out, "My son, you ought not to tell stories, even in fun. You will make dear Mr. Goodnews think very badly of your parents." "Any how, mother, it is true," said the boy. When Grayson was eleven years old, he was allowed to go to the races. Here his fondness for sport and gaming was much increased. He also saw many things that he did not understand, and some that made him shudder. His parents had given him at different times money, which he had saved, and adding to which, what he received that morning, the sum total amounted to one dollar and a quarter. The race that day was chiefly between two noted animals, Major Clark's Rabbit, and Colonel Nelson's Yellow Gray. Betting ran high. At first Grayson bet twenty-five cents in favor of Rabbit; then he bet fifty cents against twenty-five on the Yellow Gray; then he bet his remaining fifty cents against another fifty cents in favor of Yellow Gray. In the meantime he bought some beer and some cakes, and paid away twenty-five cents of his money. When he first remembered that he might lose, he thought he would not be able to meet all his engagements; but on reflection he discovered, that let who would win, he could not lose all. The race was run. Rabbit was beaten, and Grayson got his seventy-five cents, and paid what he had lost, and had now left one dollar and a half. At first he thought he would go home, and started—but a boy stepped forward and said, he could show him some tricks—that he had a rattle-come- snap, &c. Grayson went with him into the bushes, and there Grayson lost one dollar at some sort of game, became vexed, and went home. At night he would have determined never to bet any more, had it not been that some gentlemen came to his father's, and talked earnestly about their gains. Then the thought entered his mind that it was entirely owing to good luck that some succeeded, and that he would have better luck another day.
- 71. A few daysafter the races, Mr. Griffith was called to see his mother die. She had been a very worldly-minded, proud woman—but her last sickness had humbled her. With her last breath she spoke of herself as a great sinner, and of her salvation as doubtful, and most solemnly warned all her children not to follow her example. The minister at Goodcheer went over to preach the funeral sermon, and returning in company with Mr. Griffith, he thought he perceived some seriousness in his manner, and introduced a very friendly and solemn conversation on the importance of preparing for death. From that time Mr. Griffith began to change, and in twelve months he and his wife both joined Mr. Goodnews's church. They also presented their five children to the Lord. This was a great change, and was much spoken of by the villagers. It is thought the father and mother were both truly converted. The day the children were baptized, Grayson did not behave well in church, yet he dared not to do anything very wrong. The next day, when one of the boys laughed at him for being baptized, he at first thought he would say nothing, and had he done so, all would have been well. But the laugh tormented him. So in going home from school he made fun of it, and said the old people had got mighty religious. When he got home he felt dreadfully at seeing Mr. Goodnews at his father's; but he soon left the house, and took the old cat in his arms, and called the dogs, and went to chase cats in the old field. His parents with difficulty prevailed on him to attend Sabbath school. He said five days and a half in a week were enough to go to school. He also disliked to come to prayers. He was frequently out until a late hour at night, and once was found with some very bad boys in an old house on a Sabbath night, doing what he called "projecting." His parents had all along opposed the cold water men, and had allowed Grayson to have some sweetened dram in the morning out of their cups. And even after Mr. and Mrs. Griffith joined the church, it did not seem easy to conquer in a day all their prejudices against the temperance society. These things led Master Grayson to drink julaps, and punch, and even grog. But he did not drink much. He had also learned to use profane language to an extent that was very
- 72. distressing to somepious people who had heard him; but his parents supposed he never swore. When Grayson was sixteen years old, he read Hoyle on Games; and though he understood very little of what he read, he conceived that gaming must be a very profound science. Especially was this impression deepened by hearing a member of congress say, that Hoyle was as profound as Sir Isaac Newton. He read Hoyle again, and even on the Sabbath. His parents began to suffer much uneasiness about him; they sometimes wept over his case; they took great pains to make religion appear amiable—but he was eager in his pursuit of vanity. When Grayson was eighteen or nineteen years old, he became acquainted with Archibald Anderson, a most unworthy young man, of low breeding and much cunning. Archie persuaded Grayson to go a pleasuring the next Sunday—told him he had found a bee-tree, and that they would get some girls and go and take the bee-tree next Sunday. They went, and although Grayson tried to think it fine fun, it was a very gloomy day. A thousand times did he wish himself in church. At night he came in late, and went immediately to bed. Next day his father inquired where he had been. But Grayson let him understand that young people must not be watched too closely. In a day or two Mrs. Griffith became alarmed at finding in Grayson's apparel evident preparations to elope; but gentle and kind treatment soon seemed to regain his confidence. Mr. Griffith had, in the course of business, previously borrowed a thousand dollars from one of his neighbors, who had since removed to the city of Allvice—and wishing to raise his bond, he gave Grayson $1060, being the principal and interest for one year, and money to buy himself a suit of clothes, and started him to town. Grayson had never been to the city before, and his hopes were very high. On the evening of the third day's ride, he arrived in the city of Allvice, and put up in Blockley Row, at Spendthrift Hotel, next door to the sign of the Conscience-seared-with-a-hot-iron. After supper he went to the
- 73. bar-room, and askeda young man "how far it was to any place where he could see some fun." "What, the theatre," said the young man. "Any place where I can see a little fun," said he. The young man said, "follow me." Ere long they were at the door of the theatre, where Grayson saw in large letters over a door—"The way to the pit." He knew not what it meant, but said to the young man, "Don't let us go that way." "No," said his companion, "we will go to the gallery. You know they are in the gallery." Grayson knew not who was meant by the emphatic they; but following his guide, was soon in a crowd of black and white women, and young and old men. Taking the first lesson in the species of crime there taught, he stepped down a little lower, and asked to what place a certain door led. He was told, "to the boxes." Entering that door, he found many a vacant seat, and listened—but when others laughed, he saw nothing to laugh at, until the clown came on the stage. At him he laughed—he roared. Yet he felt as if he had lost something, but could not tell what it was. "In the midst of laughter the heart is sad," were words he often repeated, as he sat in a box alone. The play being ended, he endeavored to find his way to the hotel, but was greatly discomposed at remembering that his money had been left in his saddle-bags, and they not locked, and that he had not seen them since he came to town. At length he reached his lodgings, and found all safe. He went to bed, but could not sleep. Most of the night was spent in reflection, or rather in wild and vain imaginations. A little before day a well dressed gentleman was shown into the room where our young hero lay, there being two beds in the room. The new inmate took a seat, and sighed; he paced the floor; he took out his port-folio, and wrote a few words; he dropped his pen and said, "What a fool." At length Griffith (for he is now too old to be called by his given name,) ventured to inquire whether he could in any way assist his room-mate to a greater composure. "O sir," said the man, and sighed. At length the stranger said: "Eight days ago I left home with $3,600 to go to the north to buy goods. I came here day before yesterday, and to-night they have got the last cent from me at the faro bank. And now, O what a fool!—I had rather take five hundred lashes than do what I must,—write to my partner or my wife to send
- 74. me money tocarry me home." Griffith expressed regret, but of course could offer no consolation. He resolved, however, to pay the $1,060 as soon as he could find the man to whom it was due. This he accordingly did before nine o'clock next morning. The rest of the day he walked the streets. Every little while $3,600 kept ringing in his ears. At night, not having bought his suit of clothes, he went to the bar, and there found the same young gentleman who the night before had accompanied him to the theatre. Griffith took a seat by a window, and the well dressed young man came to him and said: "Young gentleman, I see you are fond of real genteel pleasure; let us go down into hell, and win those fellows' money." Perhaps more mingled emotions never agitated a bosom. In the first place he had been called a young gentleman—an honor which, though he had deserved it before, had seldom been given him. Then the idea of "real and genteel pleasure." But the very sound of "going down to hell!" He would not go in "the way to the pit" the night previous— and now could he go to hell? At length he concluded that it was a mere nickname, and that the place was really no worse than if it were called heaven, and he replied, "I don't care if I do." They both left the room and went to the stable. "Stop a minute," said Griffith, "let me see if Decatur has a good bed and a plenty to eat." In half a minute he satisfied himself that his horse fared well, and he followed his young acquaintance into one of the stalls, through which they passed by a blind door into a long, narrow and dark entry. "Follow me," said the young man. Presently they entered a large room. Griffith was struck with the abundance of good things to eat and drink, which too were all free for visiters. At a table on one side, sat an old man with a playful countenance. He rose and said: "Last night a man won $3,600 at this table." Three thousand six hundred dollars thought Griffith—and "how much had he to begin with?" said he to the old gentleman. "Only a ten dollar note," was the reply. In another part of the room, Griffith saw a young man sitting behind a table, and leaning against the wall, with his hat drawn down over his forehead, and wearing a heavy set of features. Before him on the table lay three heaps of money—one of silver—another of gold—a third of paper. Griffith eat some very fine blanc mange on the table,
- 75. and drank alittle brandy, after which he concluded he would risk ten dollars on a card. He did so, and put a ten dollar bill into his pocket. His next risk was five dollars, which he lost. With various success he spent an hour, at the end of which he had tripled his money. He then retired to his room, and slept until a late hour in the morning. Then he went to a merchant tailor, and ordered his new suit, and spent the day in musing—visiting factories—attending auctions, and laying plans for the night. "If I had held on I might have broke them," said he; "I should have gotten $3,600!" Night came, and with it a self- confident feeling peculiar to the young gambler. He returned alone through the stall into "hell," and there lost all he had but five dollars. The next night he won $150. The next night, which was to be his last in the city, he went, and for a time succeeded. Once he had $700 in pocket, but before day-light he had lost every cent he had, and making known his situation, two men who had won his money, gave him each five dollars, and advised him to leave town at day- light. That was a wretched night to Griffith. His couch was a "bed of unrest." His very dreams were startling. At daylight he paid his bill, and had remaining three dollars and a quarter. He mounted Decatur, and with a heavy heart journeyed towards the village of Goodcheer. When he found himself in sight of home, he felt in his pocket and found he had seventy-five cents. He also felt for the cancelled bond, but could not find it. Riding into the woods, he examined his saddle- bags, and found the bond in a waistcoat pocket. Seizing it with great joy, he shed a tear, and mounted again. All the way home he had thought much of the manner in which he should account for not having the new clothes. At length seeing no way of escape, from confusion at least, in case his father should inquire respecting the matter, he cherished the hope that his father would say nothing. So he paced along, and got home just in time for dinner. There was an air of affected cheerfulness in young Griffith's gait and manner, that was unusual. He did the best he could—took care early to deliver the cancelled bond—said he was not much pleased with the city, and told something of what he had seen. Next day his father asked if he had gotten the new suit. He replied that he had concluded not to get it then, and reddened very much. Mr. Griffith told his wife that he
- 76. had fears aboutGrayson. They both wept, and agreed to pray for him more than usual. In the course of time, young Griffith being twenty-one years old, left his father's, with $700 and Decatur, to seek his fortune in the West. He soon obtained employment, and in the course of two years was able to commence business as partner in a new firm. But, unfortunately, he was not satisfied in the village where he was, but broke up and went to the town of Badblood, where he opened a store. He was not long here until a quarrel commenced betwixt him and one of his neighbors. The occasion of the quarrel was a disagreement as to the beauty of a piece of music. One declared the other to have a bad taste, and this was regarded as insulting. Of course a challenge was given, and accepted. The day of combat arrived. At the first fire no blood was spilt. This was owing to the great agitation of both the combatants. At the second fire Griffith wounded his antagonist slightly, but himself received no wound. At the third fire Griffith's right arm was broken, and his antagonist was wounded in the thigh. Here the seconds and friends interfered, and declared they had fought enough. Had it not been for public opinion, they would have thought that it was enough to be shot at once a piece. But they were both content to quit, and even to drink each other's health, before they left the ground. In the course of eight or nine weeks, they were both in their usual health, and attending to their accustomed duties. The effect on Mr. Griffith's family on learning that Grayson was expected to fight, was very distressing. The day the challenge was given, Griffith wrote to his father thus: My very dear Father:—On the morning of the day on which this shall reach you in due course of mail, I shall have settled an affair of honor. I do not love to fight, because I neither like the idea of killing or being killed. If I go on the ground, I shall certainly take life or lose it. I can't help it. I should be posted as a coward, if I did not. Mr. B. will write you as soon as it is
- 77. decided. Love tomother and the children. God bless you. I can't bear an insult. Your's ever, G. GRIFFITH. An entire week was this family in suspense, when at last, by request of the father, dear Mr. Goodnews, the minister, was at the office, and got the letter and opened it, and read the account as before given. He immediately went to Mr. Griffith's, and found both the parents in bed with a high fever, and their countenances covered with wan despair. As he entered the door he tried to look cheerfully. "Grayson is dead," said the almost frantic mother. "No, he is'nt," said the minister. "Then he is mortally wounded," said she. "No, he is not," said he. "Then he is a murderer; he has killed a man! O, my first- born Grayson!" "My dear Mrs. Griffith," said the good minister, "the Lord is better than all your fears. Grayson and his antagonist are both wounded indeed, but neither mortally." "O bless the Lord, bless the Lord," said Mrs. Griffith, and swooned away. On using proper means she was restored, and became calm and quiet; but it was an hour before Mr. Goodnews could read the whole letter to her. Mr. Griffith suffered greatly, but was much occupied with the care of his wife. He really feared that things would have terminated fatally. In a few days the parents rallied, and wrote Grayson a most affectionate and solemn letter, which he never answered. The next news of importance which these parents received respecting their son was, that he was married to an amiable, though a thoughtless and giddy girl. In a year they heard that he was the father of a sweet boy. In eighteen months more they heard that he had a sweet daughter. Not long after, they heard that he made frequent and unaccountable excursions from home, and presently they heard, that on a steam boat that ran between the town of Badblood and the Bay of Dissipation, he had by gambling, lost all his money. What they had heard was true. Losing his money, he hastened home—made some arrangements for his family—disposed of as much property as was left—received five hundred dollars in
- 78. hand—left two hundredwith his wife—and with the other three hundred set out professedly to visit his parents at the village of Goodcheer. But the demon of gambling had possessed him—and Griffith in a few weeks found himself with but one hundred dollars, remaining at Spendthrift Hotel, in Blockley Row, in the city of Allvice in the Old Dominion. Here Griffith resolved to retrieve his fortunes. He sought the faro bank, and in an hour was pennyless. Poor Griffith was not far from perfect ruin. He spent the night in dreadful tossings, and in the very room where he had lodged years before. He fancied that he saw "$3,600" in flaming figures before him. In the morning he walked the streets. He watched to see whether he could recognize any old friend among the hundreds he met. He read the names on the sign-boards; he searched the morning papers; yet no bright prospect opened before him. In the afternoon he wandered into Purity Lane, and had hardly entered that street, when he saw on the knocker at the door, "Amos Kindheart." He asked a servant who was washing down the white marble steps, whether the "Reverend" Mr. Kindheart lived there, and was answered in the affirmative. Asking to be introduced into his presence, he was soon shown into the study. "Is this the Rev. Mr. Kindheart?" said he. "It is," replied the good man, "please to be seated." "Are you not acquainted with Rev. Mr. Goodnews?" "Yes sir." "Do you not also know Gregory Griffith?" "Yes sir; I stayed at his house more than a week some years ago; and if I am not deceived, this is his son Grayson, who used to exercise my horse night and morning when I was there." Mr. Kindheart expressed much pleasure at seeing him, and learned that he had a wife and two children in the town of Badblood, in the State of Misery; he also learned that he had been a merchant. Mr. Kindheart treated him very affectionately, gave him a handsome little present, invited him to dinner next day, and excused himself for that evening, as he had in a remote part of the city an engagement that could not be broken. Early next morning a little ragged servant handed Mr. Kindheart a sealed note from Griffith, stating that he had been imprudent, and requesting him to send by the bearer a sum sufficient to meet the expenses of a passage to the pleasant village of Goodcheer, from which place the amount should
- 79. be returned atan early date. Mr. Kindheart replied in a note that he had not the money then, but would get it before the next evening, when the first stage would leave, and renewed the invitation to dinner that day. Dinner came, but no Griffith was there. Several hours before it was time for the stage to start, Mr. Kindheart called with the money at Griffith's lodgings, but he was not to be seen. In a short time he called again, and then again. Still he could not be seen. The truth was, Griffith's conscience would not let him face a man from whom he knew he desired money only that he might have the means of gambling. He had no serious purpose of visiting Goodcheer. For many days Griffith loitered about the city in perfect wretchedness, and without one cent of money. At length he went to the proper city police officer, and told him that there were several gambling establishments in town, that many persons visited them, and that he could give important testimony in the case. Then going to Hardface and Takeall, two gamblers, he told them that unless they would give him $600, so that he might fairly and speedily escape, he would be retained as a witness against them at the next sessions. The gamblers agreed to give him $500, hastened his departure in a private conveyance, but started after him a man, who overtaking him in the next post town, horsewhipped him very severely. Griffith bore this rough treatment like a dog. He squealed, he cried, he howled, he danced—but he did not resist. From this time Griffith wandered about, until, in the course of a few months, he found himself again with his family. At first he seemed pleased to kiss his babes and embrace his wife; but the next day went to a faro bank in Badblood, and lost all he had—even his wife's wardrobe and toilet. At this time he resolved on destroying his own life. He went to three different shops, and procured laudanum in a quantity sufficient to take life. He went home, and as he ascended the first flight of stairs, he emptied the contents of each vial into his stomach. O woman, what an angel of mercy thou art! His wife met him at the door, with unwonted demonstrations of love. His little boy
- 80. prattled most sweetly;his little girl breathed in her crib as gently as a May zephyr. His wife told him of several pleasant and smart things which the children had said and done that day. He began to weep— then to tremble—then to dislodge the contents of his stomach. "My dear Nancy," said Griffith, "I shall be dead in a few hours, but never mind." His wife perceiving that laudanum was in his stomach, instantly prepared a potent emetic, and mixing it with a large tumbler of hot water, offered it to her husband, and he consented to drink it, supposing it could not be improper. In a few minutes, through the influence of nausea, from the effects of brandy, and from the dose just given, the stomach was emptied. Poor Griffith suffered much, but gradually recovered. None save his wife knew of the attempted violence on his own life. At length a few benevolent people proposed to him to leave Badblood, and go into the interior. He consented, and they gave him the necessary money, as he and his family entered the stage. Griffith was much affected by their kindness, especially that of one old Baptist gentleman, who said very tenderly, "God bless you all." They travelled day and night, until they were two hundred miles from the place of their recent miseries, when a violent fever and painful dysentery in their little boy compelled them to stop. The house where they stopped, though not promising much in outward appearance, was yet neat and clean. Mr. Felix, the landlord, and his wife, were intelligent, industrious and pious. They were strict temperance people, and no liquor could be had for drink within fifteen miles. Griffith of course became very cool. The first day he was very wretched; he had no employment—he had no heart to assist in nursing the sick boy. Towards evening he took a gun and walked into the field, and shot a partridge. At first he seemed pleased that he might thus promote the comfort of his little son, but then he remembered that animal food of any kind would injure him. The next day he was more miserable than ever, until about noon he saw fishing rods, and on inquiry found that there was a fish-pond not very distant. He went and angled for hours, but the hot sun had driven every fish under the banks and tussocks. He sat four long
- 81. hours, and hadnot even a nibble. He returned with a heavy heart; yet it was pleasant to more than his wife, to observe a growing earnestness and frequency of inquiry into the health of his child. The next day, being Friday, a meeting commenced at a church not three hundred yards distant from the house of their kind landlord, and by a little persuasion, Griffith was prevailed on to attend. The first sermon was very animated, and was on that text: Isaiah lii. 3: "Thus saith the Lord; ye have sold yourselves for naught, and ye shall be redeemed without money." Griffith sat on the back seat, and paid more attention than one would have supposed from his appearance. The second sermon was preached by an old gentleman, on the text, 1 Timothy, i. 15: "This is a faithful saying and worthy of all acceptation, that Christ Jesus came into the world to save sinners, of whom I am chief." Returning home, Griffith thought the preachers both affectionate and able; but he really thought some things must be personal. Indeed, the young man who had preached first, had a very dark and piercing eye, which when animated in preaching, made almost every one think he was looking all the while at him alone. When Griffith came home, he sat by his sick child, and told his wife what he had seen and heard. That night he was restless and wakeful. In the morning he took a long walk before breakfast, and at the usual hour repaired to the church. A sermon was then preached on the Cities of Refuge, and the preacher earnestly exhorted his hearers to flee for refuge to the hope set before them in the gospel. The exercises of Saturday afternoon, were prayer and singing, accompanied by short and solemn exhortations. In all these services Griffith manifested deep interest, though he said nothing, except that he detailed to his wife what he had seen and heard. He also said, that as their boy was now much improved in health, and as Mr. Felix's oldest daughter would stay at home next day, his wife must accompany him to church. Sabbath morning came, and although there seemed to be many difficulties, yet they were all surmounted, and Mrs. Griffith and her husband, for the first time in several years, went in company to the house of God. The text was, Isaiah liii. 5: "He was wounded for our transgressions, he was bruised for our iniquities; the chastisement of our peace was upon him; and with his
- 82. stripes we arehealed." During the delivery of this sermon, Griffith was seen to weep. His wife, however, had two reasons for not feeling easy. Her apparel was really poor; but she was soon relieved, by seeing that all the people were plainly attired. She also suffered much uneasiness about her son. But good Mrs. Felix had directed her eldest son to return home in an hour after the service should begin, and bring word whether all was right. Her son came with a message, which she soon, in a whisper, communicated to Mrs. Griffith. The message was, that the boy had fallen asleep—that his room had been made dark—that he seemed to sleep very sweetly, and would perhaps not wake for an hour or two. Mrs. Griffith got the message just in time to be entirely composed during the administration of the Lord's Supper, which service immediately succeeded the first sermon. It was a solemn scene. There were few dry eyes in the house. At the close of the communion service, the company of believers rose and sang that favorite spiritual song— "How happy are they Who the Savior obey," &c. Griffith and his wife both thought "how happy are they." They both hastened home, as did Mrs. Felix also. Finding their boy much better, and their kind hostess herself determining to remain at home in the afternoon, both Mr. and Mrs. Griffith returned to the church. When they came near the church they heard singing, and just as they entered the door, the congregation sung, and repeated the closing lines of a hymn as follows: "Here, Lord, I give myself away, 'Tis all that I can do." Griffith sighed, and said to himself—"O that I could give myself away, and the gift be accepted." They had just taken their seats, when the preacher announced his text in Revelation xxii. 17: "And the spirit and the bride say, come: and let him that heareth say, come: and let him that is athirst, come: and whosoever will, let him
- 83. take the waterof life freely." The sermon did not exceed forty minutes in length, yet it was a faithful, tender and solemn entreaty to all sinners, the least and the most vile, to come to Christ and live. After service, one of the ministers went home with Mr. Felix, and having observed Griffith's behavior at church, he said many good things in his presence and for his benefit. Griffith and his wife spent most of that night in solemn reflection and silent prayer. On Monday morning a neighbor called to complete some arrangements with Mr. Felix, in reference to supplying the place of their teacher, who had recently died. In an unexpected train of conversation, they were led to speak of Griffith as perhaps a suitable man. In a few days it was mutually agreed that Griffith should teach the school for the rest of that session, which was but three months. His family being provided for, he commenced his school. Yet for days and weeks, both he and his wife suffered much pain and darkness of mind. At length they both, about the same time, hoped that they had found him, of whom Moses in the law and the prophets did write. After trial of some weeks, they were admitted to the communion. The day after this event, Griffith wrote an affecting letter to his venerable parents. This letter was evidently blessed, not only to the comfort of their hearts, but also many of the pious people in Goodcheer were much affected by it. "Great is the grace, the neighbors cried, And owned the power Divine." Griffith immediately established the worship of God in his family, and rejoiced in God with all his heart. Nor was his wife a whit behind in holy delight at the change. Griffith's conversion led him to inquire into the lawfulness of gambling. He had three questions to decide. The first was, whether he should pay a debt of $60 incurred in gambling? He soon resolved to pay it, as it was the manner of contracting, and not the payment of the debt, that was the sin. The next question was, what should he do respecting the $9,000, which he found by estimate he had lost at different times? To this he could only say, that most of it was won by strangers, and by men who had
- 84. long since diedin wretchedness and poverty. He could not get it. By a careful estimate of what he had won from men whose names and residence he knew, over and above what they had won from him, and including the $500 extorted from the gamblers, by threatening to volunteer as witness against them, he found that he owed in all, rather more than $1,500. Resolving to pay the whole sum, if spared and prospered, he engaged to teach school another session of ten months; and although he could not save much of his earnings, he resolved to save what he could. How astonished was he, when a few days after he formed this purpose, as he was going to school in the morning, a gentleman hailed him as Mr. Griffith, and said: "Sir, I won from you several years ago nearly $700; there is the money, with some interest. I am a christian. I cannot keep it; there it is." With these few words, the traveller proceeded. Griffith was so amazed, that he even forgot to ask his name, or residence, or the course of his journey. Of the $700, Griffith sent $200 to the widow of a poor silly drunken man, from whom he had, not long before his complete downfall, won that amount. He sent $200 more to a young clerk, whom he had well nigh ruined as to morals and character, and from whom he had won $180 two years before. He sent $300 to the father of a little blind girl, from whose deceased brother he had won that amount, saving the interest, and requesting that it might be employed to send the blind child to the Asylum for the blind. By the kindness of Providence, other sums were restored to him, amounting in all to a few hundreds. His economy and industry, and good capacity as a teacher, also secured to him a growing income from his school—so that in a few years he had paid every debt, and restored all money obtained by gambling. He has since bought a small tract of land, and built a very neat cabin, with two apartments, upon it. He calls it the Retreat. He is now forty-three years old—still keeps a school—has a good income from his own industry—enjoys tolerable health, and has around him many of the comforts of life. His wife and children still live, and help to make him happy. His penitence and humility are deep; yet is thankfulness the reigning exercise of his heart. The
- 85. goodness and graceof God, through Jesus Christ, are themes on which he never tires. Dryden's genius was of that sort which catches fire by its own motion; his chariot wheels got hot by driving fast.—Coleridge. For the Southern Literary Messenger. LINES Written in Mrs. ——'s Album.
