if else Statement in C Program
- An if statement can be followed by an optional else statement, which executes when the Boolean expression is false.
- If the Boolean expression evaluates to true, then the if block will be executed, otherwise, the else block will be executed.
- C programming language assumes any non-zero and non-null values as true, and if it is either zero or null, then it is assumed as false value.
Sample Code
#include <stdio.h>
int main()
{
int a=10;
if(a==10)
printf("First condition is true\n");
else
printf("First condition is false\n");
}
Output
First condition is true
