Explain ‘simple if’ statement in C language
‘if’ keyword is used to execute a set of statements when the logical condition is true.
Syntax
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.
Example
Given below is the C program to execute If conditional operators −
#include<stdio.h>
void main (){
int a=4;
printf("Enter the value of a: ");
scanf("%d",&a);
if(a%2==1){
printf("a is odd number");
}
Return 0;
}Output
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.
