        {
            int input = int.Parse(userInput[0]);

                 switch (input) // what is input
            {
                case 1: //if it is 1
                    Console.WriteLine("You typed 1 (one) as the first
command line argument");
                    break; // get out of switch block
                case 2: // if it is 2
                    Console.WriteLine("You typed 2 (two) as the first

                    break; // get out of switch block
                default: // if it is not any of the above
                    Console.WriteLine("You typed a number other than
1,2 and 3");
                    break; // get out of switch block

            }
