Check given year is leap year

Write a program to check if a given year is a leap year or not.

Leap Year: A year is a leap year if it is divisible by 4. If a year is a century year then, if the year is divisible by 400 then it is a leap year, otherwise not a leap year.

Example 1:

Input :2020
Output: Leap Year

 Example 2:

Input :2010
Output: Not a Leap Year

Approach

C

#include <stdio.h>
#include <stdbool.h>
//function to check given
//year is leap or not
bool isLeapYear(int year)
{
    //if year%100==0
    if (year % 100 == 0)
    {
        //if year%400==0
        if (year % 400 == 0)
            return true;
        else
            return false;
    }
    //if year%4!=0
    if (year % 4 != 0)
        return false;
    else
        return true;
}
int main()
{
    int year = 2020;
    if (isLeapYear(year))
    {
        printf("Leap Year\n");
    }
    else
    {
        printf("Not a Leap Year\n");
    }
    return 0;
}

Java

public class LeapYear {
    public static void main(String[] args) {
        int year = 2020;
        if (isLeapYear(year)) {
            System.out.println("Year is leap year");
        } else {
            System.out.println("Year is not leap year");
        }
    }

    private static boolean isLeapYear(int year) {
        if (year % 100 == 0) {
            if (year % 400 == 0)
                return true;
            else
                return false;
        }
        if (year % 4 == 0) {
            return true;
        }
        return false;
    }
}

C++

#include <bits/stdc++.h>
using namespace std;
//function to check given
//year is leap or not
bool isLeapYear(int year)
{
 //if year%100==0
 if(year%100==0)
   {
       //if year%400==0
       if(year%400==0)
          return true;
      else 
        return false;
   }
  //if year%4!=0
  if(year%4!=0)
    return false;
  else
    return true;
  
}
int main()
{
    int year=2020;
    if(isLeapYear(year))
       cout<<"Leap Year\n";
    else
      cout<<"Not a Leap Year\n";
    return 0;
