Nested Loop: Square Of Numbers

The goal for this exercise is to give you more opportunities to practice writing nested loops, using parameters, and using return value(s).

What you need to do for this exercise

  1. In the starter project, add code to the the Square_Of_Numbers_Parameters_Return class, so that the RunExercise method will create an instance of the SquarePrinter class.

  2. You should then ask the user for the width and height of a rectangle to print.

  3. The PrintRectangle method on the SquarePrinter class (you will need to add and implement this method) will print out a hollow rectangle of the height & width specified. This method must also return the number of stars that were printed.

  4. The RunExercise method (and ONLY the RunExercise method) will print out how many stars were printed.

Here's a sample transcript, with user input displayed like this:

                Width? 5
                Height? 4
                *****
                *   *
                *   *
                *****
                Total number of stars: 14
