#include <stdio.h>
#define LEAP_YEAR(year) ((0 == (year) % 4 && 0 != (year) % 100) || (0 == (year) % 400)) ? 1 : 0

int main(int argc, char *argv[])
{
    int year;
    printf("please input year number:");
    scanf("%d",&year);
    
    if (LEAP_YEAR(year))
    {
       printf("%d year is a leap year!",year);
    }
    else
    {
        printf("%d isn't a leap year!",year);
    }
    
    system("pause");
    return 0;
}
