C Program to Check Year is a Leap Year or Not

How to Check Year is a Leap Year or Not in C:-

In this program we have to find the year is a leap year or not. Generally  we assume that year is exactly divisible by 4 is a leap year. But it is not only in this case 1900 is divisible by 4. But it  is not a leap so it that case we follows these conditions   

• It is exactly divisible by 100
• If it is divisible by 100, then it should also exactly divisible by 4
• And it is divisible by 400  

These all conditions are true year is a leap year.

ALGORITHMS:-

Step 1. Initialize variable “year” to find leap year.

Step 2. Take input from User.

Step 3. We use this condition ((year%4==0)&&            (year%100!=0)) || (year%400==0)) to check the year is Leap or not.

Step 4. It is true display year is a leap year.

Step 5. It is false display year is not a leap year.

Step 6. Stop.

CODE: -

#include<stdio.h>
int main()
{
    int year;
    printf("Enter any year: ");
    scanf("%d",&year);
    if(((year%100!=0)&&(year%4==0))||(year%400==0))
    {
        printf("year is leap year");
    }
    else
    {
        printf("Year is not a leap year");
    }
    return 0;
}
