* Name        : Validate Input Using do-while Loops

* Author      : Isaac Lavana

* Created     : 10/13/2023

* Course      : CIS 169 - C#

* Version     : 1.0

* OS          : Chrome OS

* IDE         : Visual Studio 2022 Online Replacer

* Copyright   : This is my own original work based on

*               specifications issued by our instructor

* Description : The user has to put in a number greater

  than 7 and less than 32. If the user does this, the

  code stops, but if the user chooses to disobey, then

  the code will continute to run until the user does so.

* Input: Any number <32 and >7...

* Output: Enter a number between 7 and 32: (user input)

          Good job, (user input) is a valid...

* Academic Honesty: I attest that this is my original work.

* I have not used unauthorized source code, either modified or

* unmodified. I have not given other fellow student(s) access

* to my program. I confidently assert do while loop is a 

* strategy given to us by out instructor to use on this code. 

* In all seriousness, there is no more  information to disclose

* besides what is already given. This message is to the

instructor Anita Wood...
