C :

#include<stdio.h>
int main(){
	int x;
	scanf("%d",&x);
	if(x%2==0){
		printf("%s","y e s");
	}else{
		printf("%s","n o");
	}
	return 0;
} 

C++ :

#include<iostream>
using namespace std;
int main(){
	int x;
	cin>>x;
	if(x%2==0){
		cout<<"y e s"<<endl;
	}else{
		cout<<"n o"<<endl;
	}
}

	

Python :

r = int(input())
if r % 2 == 0 :
   print('y e s') 
else:
    print('n o')
