Using the above code...

Create a Menu Driven Program [see below] to ask for how many repetitions you want for each LOOP TYPE.

Your Menu should be this:

Repetition Selection for Looping.

1. While Loop - how many?

2. Do Loop – how many?

3. For Loop – how many?

4. Quit!

You must use a CASE/SWITCH, WITH A QUIT AND DEFAULT ERROR MESSAGE FOR LOOPING INCORRECT CHOICES.

All Error Message must be relevant and be printed on the screen.

A new Menu must be displayed on the console each time a menu choice is made.

All choices must be tested and printed in the text file.

You should use the Tab command [ ] to center your menu on the console and the to move it down to the center.
