Switch Statement Problem
Hey everyone,
So I'm trying to write a sort of piggybank code for a school project. It's supposed to let you deposit, withdraw, and see what coins you have.
My professor wants us to use switch statements, and I thought I had done them correctly, but now, the program isn't working.
Also, the program is not supposed to accept negative values when depositing/withdrawing, yet it still does. Can anyone help?
I was wondering if anyone could provide some insight as to why this isn't letting me input an option (1-4).
My code is as follows:
1
2
3
4
5
6

Any help is appreciated. Thanks!

your case labels are char so choice should be char
Wow, I can't believe I missed that.
Thank you!
Is there anything you can suggest I do about the negative values problem?
