  • If statement in C is known as a decision-making statement.
  • It makes a decision based on the condition given.
  • It is followed by an optional else statement.
  • The block of codes inside the if statement is executed only if the given condition is true.
  • Codes inside the curly braces are skipped if the condition evaluates to false, and the code after the if statements are executed.
  • Code inside parenthesis of the if statement is true, everything within the curly braces is executed.
  • If condition true evaluates to true, code runs the printf execution.

    • Syntax

    if (testCondition) {
       // statements
    }

    Sample Code

    #include <stdio.h>
    #include <stdbool.h>

    int main(void) {
        if(true) {
            printf("Statement is True!\n");
        }

        return 0;
    }

    Output

    Statement is True.

    if..else statements

    • In an ..else statement, code inside the brackets is executed only if the statement condition evaluates to true.
    • If the condition in the if statement evaluates to false, the code inside the else statement is executed.

    The construct “if (condition) then A else B” is used for which of the following purposes ?

    A. Decision making

    B. Iteration

    C. Recursion

    D. Object oriented programming

    Answer : A. Decision making

    Explanation:

    If-Else for Decision Making:

    • The if statement alone tells us that if a condition is true it will execute a block of statements and if the condition is false it won’t. But what if we want to do something else if the condition is false. Here comes the else statement. We can use the else statement with if statement to execute a block of code when the condition is false.
