OK! I almost made my calculator me proof! (read: idiot proof; ...if you knew me, that'd be funnier. Err... wait. Actually after all of this, you'll probably find it funny. Well, you will after my question, anyway... I like questions. You know what my favorite question is? ... ...Ok, now you think I'm an idiot.}
Anyway, I have one last problem with my calculator. All of the "Improper value" warnings only work if the improper value is a number. If it's any other character, my program crashes.
This is because the variables that this "Improper value" warning acts on is an integer. ¬_¬
So what can I define the variable as so that it works for both characters and numbers?
