  Variables Memory location Variable name Variableis a name given to a memory location which acts as a container for storing data. Syntax: 1 let mut age=15; 2 age=16;

  Constants Constants are fixedvalues that do not change during execution time. Syntax: 1 2 const x: f32 = 1.54; Examples of constants

  Compound Data Types- Arrays An array is a data structure that contains a list of elements. These elements are all of the same data type, such as an integer or string. Syntax: 1 2 let arr=[ ]; 0 1 2 3 4 5 6
• 13.
  Compound Data Types- Tuple A tuple is a data structure that contains a list of elements. These elements can be of different data type, such as an integer or string. Syntax: 1 2 let tup: (i32, f64, u8) = (200, 1.2, 2); 0 1 2 3 4

  Strings A string isbasically an array of characters. Syntax: 1 2 let mut s = String::new( ); E D U R E K A 0 1 2 3 4 5 6

  Functions A function isa block of organized, reusable code that is used to perform a single, related action. Functions Predefined Functions User Defined Functions Syntax: 1 2 3 fn greetings( ) { println!(“Hello everyone!”); } name of the function enter parameters here

  Conditional Statements -If Conditional statement is a set of rules performed if a certain condition is met. It is like an ‘If-Then’ statement. (IF a condition is met, THEN an action is performed) If code End Start True Condition False Exit Syntax: 1 2 3 if(condition) { statement; }
• 17.
  Conditional Statements –If else Conditional statement is a set of rules performed if a certain condition is met. It is like an ‘If-Then’ statement. (IF a condition is met, THEN an action is performed) If code End Start True Condition False Else if code Syntax: 1 2 3 4 5 6 if(condition) { statement a; } else { statement b; }

  Conditional Statements –Else if Conditional statement is a set of rules performed if a certain condition is met. It is like an ‘If-Then’ statement. (IF a condition is met, THEN an action is performed) If code End Start True Condition False Else if code Syntax: 1 2 3 4 5 6 7 8 9 if(condition) { statement a; } else if(condition) { statement b; } else { statement c; }

  Loop Loop is usedto repeat a specific block until some end condition is met. Start Conditional Code Condition False True End loop Syntax: 1 2 3 loop { statements; }
• 20.
  For Loop Repeatedly executesthe loop code while a given condition is TRUE. It tests the condition before executing the loop body. Start Execute Statement (s) End Next item from sequence If no more itemsItem from sequenceSyntax: 1 2 3 4 for var in expression { block statements; }
• 21.
  While Loop While thecondition is true, the code within the loop is executed. Start Conditional Code End True False Condition Syntax: 1 2 3 while(condition) { loop code; }
• 22.
  Ownership When a blockof code owns a resource, it is known as ownership. • Every value has a variable associated which is the owner • There can only be one owner at a time • If the owner goes out of scope, the value associated with it is destroyed RULES Example: 1 2 let x=12; let y=x;
• 23.
  Structure A structure isa user-defined data type that consists of variables of different data types. Syntax: 1 2 3 4 5 struct Student { variable: data-type; variable: data-type; } Name Age Father’s name

  Enum Enum is acustom data type which contains some definite values. Syntax: 1 2 3 4 5 enum enum_name { variant1, variant2, } Stop Ready Go Traffic Signal
• 25.
  Modules A module isa namespace which contains the definitions of the functions or its types. A module is a collection of items such as functions, traits, structs, blocks. Syntax: 1 2 3 mod module_name { module body } • mod - declares the new module • pub - makes the visibility modifier as public & accessible outside the namespace • use - to import the module into local scope Keywords used in modules:

  Vectors Vectors allow youto store more than one value in a single data structure that puts all the values next to each other in memory. Syntax: 1 2 let v : Vec<i32> = Vec::new( ); • Stores values of the same data type • It is denoted by Vec<T> • It is a growable array Key points of Vectors:
