#include<iostream>

using namespace std;

int main()

{

    int y;

    cout<<"Enter year : ";

    cin>>y;

    if((y%4==0 && y%100!=0) || (y%400==0))

    {

        cout<<endl<<y<<" is a leap year";

    }

    else

        cout<<endl<<y<<" is not a leap year";

    return 0;

}

OUTPUT 1:

Enter year : 2018

2018 is not a leap year
