Input value of a: 20
Input value of b: 15
のように実行結果で表すにはどのような文にすればいいですか
。emacsですが

#include <stdio.h>
#include <stdlib.h>

int main(void){
    int a,b;
    
    printf("Input value to a:");
    scanf("%d",&a);
    printf("Input value to b:");
    scanf("%d",&b);

    printf("Input value of a: %d\n", a);
    printf("Input value of b: %d\n", b);

    return EXIT_SUCCESS;
}

#include <iostream>

using namespace std;

int main(void){
    int a,b;
    
      cout << "Input value to a:";
      cin >> a;
      cout << "Input value to b:";
      cin >> b;

      cout << "Input value of a: " << a <<   endl;
      cout << "Input value of b: " << b <<   endl;

    return EXIT_SUCCESS;
}

using System;

class SampleProg1{

    static void Main(){
        int a, b;
    
        Console.Write("Input value to a:");
        a=Int32.Parse(Console.ReadLine());
        Console.Write("Input value to b:");
        b=Int32.Parse(Console.ReadLine());
    
        Console.WriteLine("Input value of a: {0}", a);
        Console.WriteLine("Input value of b: {0}", b);
    }
}
