  Introduction of programming Whatis programming? Programming is writing computer code to create a program, to solve a problem. Programs are created to implement algorithms . Algorithms can be represented as pseudocode or a flowchart , and programming is the translation of these into a computer program.

  What is program? A program is a set of instructions that a computer follows in order to perform a particular task. [computing] The chances of an error occurring in a computer program increase with the size of the program

  What is programmer? A programmer is someone who writes/creates computer software or applications generally by providing instructions (commonly through the use of a specific programming language) to the computer or by configuring already existing code (such as a framework or existing code base).

  Programming Methodologies -Introduction When programs are developed to solve real-life problems like inventory management, payroll processing, student admissions, examination result processing, etc. they tend to be huge and complex. The approach to analyzing such complex problems, planning for software development and controlling the development process is called programming methodology. Types of programming methodology

  •A procedural languageis a sort of computer programming language that has a set of functions, instructions, and statements that must be executed in a certain order to accomplish a job or program. In general, procedural language is used to specify the steps that the computer takes to solve a problem. Computer procedural languages include BASIC, C, FORTRAN, Java, and Pascal, to name a few. To create programs, they use variables, conditional statements, and functions that permit a computer to process and provide the desired output. •Although it allows the users to give computers instructions in a natural language like Chinese, French, or English, computers are unable to understand human communication. Therefore, users cannot do that. Human intelligence can create ambiguities in communication with natural language, but a computer needs a clear instruction, mathematically precise communication system. Procedural language

  Functional programming isa programming paradigm in which we try to bind everything in pure mathematical functions style. It is a declarative type of programming style. Its main focus is on “what to solve” in contrast to an imperative style where the main focus is “how to solve”. It uses expressions instead of statements. An expression is evaluated to produce a value whereas a statement is executed to assign variables. Those functions have some special features discussed below. Functional Programming is based on Lambda Calculus Functional programming language

  Structured programming, ormodular programming, is a programming paradigm that facilitates the creation of programs with readable code and reusable components. All modern programming languages support structured programming, but the mechanisms of support -- like the syntax of the programming languages -- vary. When modules or elements of code can be reused from a library, it may also be possible to build structured code using modules written in different languages, as long as they can obey a common module interface or application program interface specification. structured programming language

  Modular programming isdefined as a software design technique that focuses on separating the program functionality into independent, interchangeable methods/modules. Each of them contains everything needed to execute only one aspect of functionality. Talking of modularity in terms of files and repositories, modularity can be on different levels - Libraries in projects Function in the files Files in the libraries or repositories Modularity is all about making blocks, and each block is made with the help of other blocks. Every block in itself is solid and testable and can be stacked together to create an entire application.
