I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability.

using System;
 
class Program
{
 
    static void Main(string[] args)
    {
 
        int num1;
        int num2;
        string operand;
        float answer;
 
        Console.Write("Please enter the first integer: ");
        num1 = Convert.ToInt32(Console.ReadLine());
 
        Console.Write("Please enter an operand (+, -, /, *): ");
        operand = Console.ReadLine();
 
        Console.Write("Please enter the second integer: ");
        num2 = Convert.ToInt32(Console.ReadLine());
 
        switch (operand)
        {
 
            case "-":
                answer = num1 - num2;
                break;
 
            case "+":
                answer = num1 + num2;
                break;
 
            case "/":
                answer = num1 / num2;
                break;
 
            case "*":
                answer = num1 * num2;
                break;
 
            default:
                answer = 0;
                break;
          }
        Console.WriteLine(num1.ToString() + " " + operand + " " + num2.ToString() + " = " + answer.ToString());
        Console.ReadLine();
 
    }
 
}

Result:

Please enter the first integer: 50

Please enter an operand (+, -, /, *): /

Please enter the second integer: 5

50 / 5 = 10
