LAB $2$: Instructions

Implement these changes $/$ additions over the last assignment $($Lab $\backslash$#$1).$ You may work your own solution to Lab $\backslash$#$1,$ or use the one posted on Blackboard $($check the corresponding assignment link to find the solution$).$

The details of the methods are $($mostly$)$ not provided. It is up to you to find a suitable implementation. A solution will be provided afterwards, so you may continue from the solution file for future labs $\backslash$& assignments.

Zip your entire project folder and upload the $.$zip file to Blackboard. Have fun!!! user class; using System;
