Write a C Program to Check Leap Year

Saroj July 11, 2022

In this tutorial learn how you can write a c program to read a year and determine if it is leap year or not.

A leap year is exactly divisible by 4 except for century years. Century years are those years ending with 00. The century year is a leap year only if it is perfectly divisible by 400. 

We are using if else and else if condition in two different ways.

C programming is a powerful general-purpose programming language. It can be used to develop software like operating systems, databases, compilers, etc.

Write a Program to Check a Number Odd or Even using Bitwise Operator

Here is the code to read a year and determine if it is leap year or not in C programming.

First Method to Check Leap Year 

#include <stdio.h> //WAP to read a year and determine if it is leap year or not.
int main(){
    int year;
    printf("Please enter year:");
    scanf("%d",&year);
    if(year%4==0){
       if (year%100==0){  //Checking if it is century year or not
        if(year%400==0){
            printf("%d is leap a year.",year);
        } else printf("%d isnot a leap year.",year);
       } else  printf("%d is leap a year.",year);
    }  
    else printf("%d isnot a leap a year.",year);
    return 0;
}

int main(){
    int year;
    printf("Please enter year:");
    scanf("%d",&year);
    if((year%4==0) && ((year%400==0) || (year%100!=0)))
        printf("%d is leap year",year);
    else printf("%d isnot a leap year",year);
    return 0;
