Damn, you guys are really helpful. I know the indentation is bad. Haven't even tried lookingt at it yet. And I was instructed to use C and C++. Thanks for all the advice.

>I know the indentation is bad. Haven't even tried lookingt at it yet.

Let me be candid with you. You say you haven't even tried looking at it yet. So presumably you are expecting someone else to just swan in, fix your atrocious indentation style, your mis-match of c and c++ and compiler errors for absolutely nothing.

One word --"NO!"

No, I just wanted help with the syntax errors, like I said. I dont want anyone to fix my indentation. And the mismatch is not something to be fixed. Like I said, I need to do that in this class.

If you'd fix the indentation issues, most of the syntax errors would disappear -- which is why it is often mentioned.

For me, crappy indentation means relatively little. I'll just hit my 'beautify' button and be done with it. When it is important is when you are new and learning. If you avoid it -- save it 'til later "once it's working" -- you are making things several times more difficult for yourself and only yourself.
