Alright I finally fixed and compiled it, but now when I try to run it, it displays three 0s instead of the numbers it's supposed to. It should be taking x * x (or 5*5) and display 25, but it comes up as 0 for all three functions.
(Yes, I know it's quite a sucky thing to do, naming my files like that. Sorry if it upset you.
How can I get it to show the numbers it's supposed to be showing?
