What is Leap Year?

A leap year is an year, occurring once every four years, which has 366 days including 29 February as an intercalary day.

Approach:

A year is a leap year if:

• either, it is divisible by 400
• or, divisible by 4 and not divisible by 100.

So we check if the given year is

• divisible by 400 or,
• divisible 4 and not divisible by 100

Code:

#include<stdio.h>
int yyear(int year)
{
    if(year % 400 == 0)
    return 1;
    if(year % 100 == 0)
    return 0;
    if(year % 4 == 0)
    return 1;
    return 0;
}
int main()
{
    int year=1996;
    if(yyear(year))
    printf("Yes, it is a leap year");
    else
    printf("No, it is not a leap year");
}
