Part A-3: ReadString Create a method called ReadString that will ask the user for a string. Instead of returning the value like in ReadInteger, you should use pass by reference to get the string back to the caller. The method should show a prompt, read the user's input, store the input in the ref parameter. If the user does NOT enter a string, show an error message to them, show the prompt again and ask for the user's input. You'll need a loop for this. Do not return until the user enters something. You should use the IsNullOrEmpty or the IsNullOrWhiteSpace methods of the string class to check if the string is empty.
