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

    // True if num is perfectly divisible by 2
    if(num % 2 == 0)
        printf("%d is even.", num);
    else
        printf("%d is odd.", num);

    {
        printf("%d is an even integer", Num);
    }
    else
    {
        printf("%d is an odd integer", Num);
    }
