I need help on my assignment. Below are the instructions and below the instructions are my current code

Using Assignment 2, add both Data Validation and Exception handling.

Make sure to handle at least 1 specific exception and the generic exception in each button. Try to make the specific exception applicable to the task. For instance, don't use DivideByZeroException for the multiplication button as this can't occur doing multiplication.

Put your Data Validation into methods. How you choose to call the methods is up to you.

I'll upload a starting point (completed assignment 2) on Friday night (Feel free to use yours and start sooner). Please make sure your assignment 2 is turned in before then or else you will receive a zero for that assignment.

Turn in the zip folder of the project and a screen shot of the project catching an exception or the Data Validation preventing an exception.
