Any year is entered through the keyboard. Write a program to determine whether the year is a leap year or not.

#include <stdio.h>

void main ()

{

      int a ;

      printf("enter year= ");

      scanf("%d", &a);

      if(a%4==0,a%100!=0)

            printf("leap year");

      else if(a%400==0)

        printf("leap year");

      else

        printf("not leap year");

     

}
