C Program to check whether an integer entered number by the user is odd or even.

I have used DEV-C++ compiler for debugging purpose. But you can use any C programming language compiler as per your availability.

#include <stdio.h>
int main()
{
    int number;
    printf("Enter a number: ");
    scanf("%d",&number);

    // True if remainder is 0
    if( number%2 == 0 )
        printf("%d is an even number.",number);
    else
        printf("%d is an odd number.",number);
    return 0;
}

Result:

Enter a number: 101

101 is an odd number.
