Using default arguments, write a function that asks the user for a number and returns that number. the function should accept a string prompt from the calling code. if the caller does not supply a string prompt, the function should use a generic prompt. next, using function overloading, write a function that achieves the same result.

Here's a solution in C#:

        static int AskNumber(string prompt = "Please enter a number: ")        {            int number;            bool numberOK = false;
            do            {                Console.WriteLine(prompt);                var numberString = Console.ReadLine();                numberOK = int.TryParse(numberString, out number);            } while (!numberOK);
            return number;
        }

If you want to replace the default argument approach with function overloading, you change the function heading to:

        static int AskNumber(string prompt )        {
            // rest stays the same
        }

And add this overload:

        static int AskNumber()        {            return AskNumber("Please enter a number");        }

The compiler will figure out which one to call, so both these will work:

        static void Main(string[] args)        {            AskNumber("Input some digits");            AskNumber();        }

Yes, by adjusting the boot order.
