Use a switch statement to do the math.Д¬onsole.WriteLine($'Your result: = ' + (num1 / num2)) ДЄfter you replace the code, the section with the switch statement should look similar to the following screenshot: Num2 = Convert.ToInt32(Console.ReadLine()) Д¬onsole.WriteLine('Choose an option from the following list:') Ask the user to type the second number.Д¬onsole.WriteLine('Type another number, and then press Enter') Num1 = Convert.ToInt32(Console.ReadLine()) Ask the user to type the first number.Д¬onsole.WriteLine('Type a number, and then press Enter') Display title as the C# console calculator app.Д¬onsole.WriteLine('Console Calculator in C# ') Д¬onsole.WriteLine('- ') Declare variables and then initialize to zero.
