C :

#include<stdio.h>

void main(){
	int n;
	scanf("%d",&n);
	
	if(n>=10&&n<=99&&n%2==0){
		printf("%s","Yes");
	}else{
		printf("%s","No");
	}
}

C++ :

#include <bits/stdc++.h>
using namespace std;


int main(){
	int n;
	cin>>n;
	if(n >= 10 && n <= 99 && n % 2 == 0){
		cout<<"Yes";
	} else{
		cout<<"No";
	}
}

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 n = sc.nextInt();
		if(n%2==0 && n>=10 && n<100){
			System.out.println("Yes");
		}else{
			System.out.println("No");
		}
		sc.close();
	}

}

Python :

n = int(input())
if 10 <= n < 100 and n % 2 == 0:
    print('Yes')
else:
    print('No')
