Write a c program to check even or odd

In this example, you will learn to check whether a number entered by the user is even or odd.

An even number is an integer that is exactly divisible by 2. For example: 0, 8, -24

An odd number is an integer that is not exactly divisible by 2. For example: 1, 7, -11, 15

Program to Check Even or Odd

#include <stdio.h>
int main() {
    int num;
    printf("Enter an integer: ");
    scanf("%d", &amp;num);
    // true if num is perfectly divisible by 2
    if(num % 2 == 0)
        printf("%d is even.", num);
    else
        printf("%d is odd.", num);
    
    return 0;
}

Out Put

Enter an integer: -7
-7 is odd.

In the program, the integer entered by the user is stored in the variableĀ num.

Then, whether num is perfectly divisible by 2 or not is checked using the modulus % operator.
