#include <stdio.h>
int main(){
int year;
scanf("%d",&year);
if(year%400==0||(year%4==0&&year%100!=0))
printf("Yes\n");

printf("No\n");
return 0;}

C++ :

#include<iostream>
using namespace std;
int main()
{
    int y;
    cin>>y;
    if (y%4==0&&y%100!=0||y%400==0)
        cout<<"Yes"<<endl;
    else cout<<"No"<<endl;
    
    return 0;
