What is Leap Year?

A year that has 366 days is called a leap year.

A year can be checked whether a year is leap year or not by dividing the year by 4, 100 and 400. If a number is divisible by 4 but not by 100 then, it is a leap year. Also, if a number is divisible by 4, 100 and 400 then it is a leap year. Otherwise the year is not a leap year.

This is a very simple program for beginners to understand how if-else condition works and how to check leap year in c programming language. 

C Programming Examples:

1. Write a C Program to Check Leap Year

2. C program to Check Leap Year

3. How to Check Leap Year in C Programming

C Program to Check Leap Year :

#include<stdio.h>

int main()

{

  int year;

  printf("Enter the year you want to check\n");

  scanf("%d",&year);

  if(year%400==0)

  {

    printf("%d is leap year\n",year);

  }

  else if(year%100==0)

  {

    printf("%d is not a leap year\n",year);

  }

  else if(year%4==0)

  {

    printf("%d is a leap year\n",year);

  }

  else

  {

    printf("%d is not a leap year\n",year);

  }

return 0; 

}

Output: 

Enter the year you want to check

2017

2017 is not a leap year

Explanation of Checking Leap Year in C Programming :

Initialization of variable 'year' for taking user input.

Then prompting user to give the year of his interest.

Now we check whether the year is divisible by 400 or 100 or 4

If the variable is divisible by

400 then it is leap year(ex: 2000,2400)

100 then it is not a leap year.(ex: 2100 which is divisible by 4 but not with 400)

4 then it is leap year.

Then printing the corresponding printf.
