Write a C Program to check whether number is EVEN or ODD

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

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

To check whether an integer is even or odd, the remainder is calculated when it is divided by 2 using modulus operator %. If remainder is zero, that integer is even if not that integer is odd.

Below is the source code for C Program to check whether number is EVEN or ODD which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C Program to check whether number is EVEN or ODD  */

#include <stdio.h>
int main()
{

    int num;

    printf("Enter an integer number :: ");
    scanf("%d",&num);

    /*If number is divisible by 2 then number
    is EVEN otherwise number is ODD*/

    if(num%2==0)
        printf("\n%d is an EVEN number.",num);
    else
        printf("\n%d is an ODD number.",num);

    return 0;
}

OUTPUT : :

First Run:

    Enter an integer number: 27
    
    27 is an ODD number.

Second Run:

    Enter an integer number: 88
    
    88 is an EVEN number.

Above is the source code for C Program to check whether number is EVEN or ODD which is successfully compiled and run on Windows System.The Output of the program is shown above .
