error C2062: type 'void' unexpected

Demesthones (8)
Hey guys, I looked around a bit on google for a way to fix this error, but came up with nothing so I figured I'd ask some people that know what they're talking about (that's you).

So once again, the error is "error C2062: type 'int' unexpected", and it has something to do with the 'heat' function.
If anyone knows how to fix this, It would be a great help.

Edit: Sorry, made it all code format

It would help if you told us what line the error was on.

Also, this isn't the source of your error, but your while loops probably meant to be while(num == 2) (note: == for comparison, not = for assignment)

EDIT: also, you shouldn't call main. Ever.

And the code you posted compiles fine without any errors for me (assuming 'menu' is properly declared somewhere).

Oh, sorry bout that. Line 44

And thanks for catching that other mistake too.
Disch (13742)
There's nothing wrong with line 44 or any of the surrounding lines. You shouldn't be getting an error.

Are you sure this is the code that is giving you the error? Did you post code that's different from what you're actually compiling?
Demesthones (8)
So here's all the code. I'm not really sure why anything other then what I posted earlier would cause the error because it really doesn't interact with 'heat' at all, though I dont really know what to look for to fix this error.

Error on line 290 of the second part

There are a few things in there that I just caught - breaks and some mis named variables but that's all stuff that I just added and fixed. So when I try to compile now, these are the errors that I get

error C2062: type 'void' unexpected - line 194 part 2
error C2143: syntax error : missing ';' before '{' - line 195 part 2
error C2601: 'heat' : local function definitions are illegal - line 290 part 2
this line contains a '{' which has not yet been matched - line 3 part 2
fatal error C1075: end of file found before the left brace '{' at 'Cornejo_Tanner Final.cpp(230)' was matched - line 1 part 1 (This one I've been getting for a while, and it doesnt make sense. At first it pointed me to the end of the program, then up there to the top. I dont get why it points to the preprocessor stuff)

Looks like the big switch in trigonometry() is missing the ending }.

Aha, well that fixed all of the other problems, or at least they arent showing up in the debug at the moment, but now I have these problems:

I was getting these earlier int he week and was totally clueless on how to fix them.

The definitions of sound, light, madLib, music and displayLoop are missing.

The definition of derivative should probably be called derivatives because that is the name you have used in the rest of the code.

Ooooh I see what I did wrong. Fixed it and it works. Thanks a ton dude, you're a lifesaver.
