求赞，谢谢！

C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int a;
	cin>>a;
	if(a%4==0&&a%100!=0||a%400==0)cout<<"Yes"<<endl;
	else cout<<"No"<<endl;
	return 0;
}

Python :

# coding=utf-8
x = int ( input () )
if(x % 4 == 0 and x%100 != 0):
    print ("Yes")
elif(x % 400 == 0):
        print ("Yes")
else:
    print("No")
