The year is divisible by 400
The year is divisible by 4 but not by 100

Approach: Check if the year is divisible by 4 or 400 but not by 100 then it is a leap year.

Code

#include <bits/stdc++.h>
using namespace std;

// Function to check if a year is a leap year
bool yyear(int year) {
    // If the year is divisible by 400, it's a leap year
    if (year % 400 == 0)
        return true;

    // If the year is divisible by 100 but not by 400, it's not a leap year
    if (year % 100 == 0)
        return false;

    // If the year is divisible by 4, it's a leap year
    if (year % 4 == 0)
        return true;

    // Otherwise, it's not a leap year
    return false;
}

int main() {
    int year = 1996;  // Year to check

    // Check if the year is a leap year
    if (yyear(year))
        cout << "Yes" << endl;  // Output "Yes" if it's a leap year
    else
        cout << "No" << endl;  // Output "No" if it's not a leap year
}
