C :

#include<stdio.h>
int main(){
	int a;
	scanf("%d",&a);
	if(a%2==0){
		printf("%s","yes");
	}
	return 0;
	
}

C++ :

#include<bits/stdc++.h>
using namespace std;
int main()
{
	int a;
	cin>>a;
	if(a%2==0){
		cout<<"yes";
	}else{
		cout<<"";
	}
	
	return 0;
}

Pascal :

var a:longint;
begin
read(a);
if a mod 2=0 then write('yes');
end.

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner sc = new Scanner(System.in);
		int a = sc.nextInt();
		if(a % 2 == 0){
			System.out.println("yes");
		}else{
			System.out.println();
		}
		sc.close();
	}

}

Python :

a=int(input())
if a%2==0:
    print("yes")
