Explain ‘simple if’ statement in C language

CServer Side ProgrammingProgramming

‘if’ keyword is used to execute a set of statements when the logical condition is true.


The syntax is given below −

if (condition){
   Statement (s)

Working of ‘simple if’ statement

  • The statement inside the if block are executed only when condition is true, otherwise not.

  • If we want to execute only one statement when condition is true, then braces ({}) can be removed. In general, we should not omit the braces even if, there is a single statement to execute.

  • When the condition is true the braces ({}) are required to execute more than one statement.


Given below is the C program to execute If conditional operators −

 Live Demo

void main (){
   int a=4;
   printf("Enter the value of a: ");
      printf("a is odd number");
   Return 0;


You will see the following output −

Run 1: Enter the value of a: 56
a is even number
Run2: Enter the value of a: 33

Here, if condition becomes false, as a result, statement inside the if block is skipped.
