You will need to create two separate projects. Use switch to develop the first project, use if else if else to develop the second project. Submit two Console app to dropbox. Create a Console App. - In main() 1. Create 4 variables: firstOperand(double), secondOperand(double), result(double), oprt(string) (25\%) firstOperand = Convert. ToDouble ( Console. ReadLine ()); oprt = Console.ReadLine () 2. switch (oprt) ( 25%) case "+": Console. WriteLine("Addition: {0}+{1}={2} ", firstOperand, secondOperand, result = firstOperand + secondOperand); break; case "-": case "*": case "/": default: Console.WriteLine("You did not enter a correct operator, no calculation was done."); break; 3; Redo the same program, use if else if else to make it. - In main() 1. Create 4 variables: firstOperand(double), secondOperand(double), result(double), oprt(string) (25%) 2. (25%) if () else if O else if O else if O else
