                    Console.Write("Enter the number of times to print \"Yay!\": ");
                    string count = Console.ReadLine();
                    int counter = int.Parse(count);
                    if (counter <=0)
                    {
                        Console.WriteLine("You must enter a whole number.");
                        continue;
