## Q. C Program to Check Whether the Given Year is Leap Year or Not.

Here you will find an algorithm and program in C programming language to check whether the given year is leap year or not. First let us understand what is leap year?

**Explanation : **A leap year is a calendar year that contains an additional day added to keep the calendar year synchronized. A leap year is exactly divisible by 4, except for the century years (the years ending with 00). Century year is a leap year only if it is completely divisible by 400.

**For Example : **2012 is Leap Year, 2014 is not a leap year.

## Leap Year Algorithm

START Step 1 → Initialize variable year Step 3 → Check if year is divisible by 4 but not by 100, DISPLAY "leap year" Step 4 → Check if year is divisible by 400, DISPLAY "leap year" Step 5 → Otherwise, DISPLAY "not leap year" STOP

# C Program To Check Leap Year

#include <stdio.h> int main() { int check_year=1998; if (check_year % 4 == 0) { if (check_year % 100 == 0) { // the check_year is a leap year if it is divisible by 400. if (check_year % 400 == 0) printf("%d is a leap year.", check_year); else printf("%d is not a leap year.", check_year); } else printf("%d is a leap year.", check_year); } else printf("%d is not a leap year.", check_year); return 0; }

#### Output

1998 is not a leap year.
