This are no longer valid C++. Use this instead:

#include <cstdio>
#include <iostream>
#include <cstdlib>

using namespace std;

>void main()
No! void main is not, and never has been, correct C++. main returns int:

int main()

>int ave, 1st, 1:2, 2:2, 3rd, pass, fail;
Okay, four of those seven identifiers are illegal. A valid identifier cannot begin with a digit and : isn't an option anywhere.

Before going any further, I'll recommend that you get a book on C++. If you already have one, I'll recommend that you actually read it.

Uh.... this looks like [bad] psuedo-code to me... which you probably copied, thus making it not yours (at least in terms of origin).

This question is so foolish and remedial, it'd do you (and the rest of humanity) some good to figure it out on your own methinks. I mean come on... void main()?

#include <iostream>
#include <cstdlib>

using namespace std;

Besides, is it even necessary to use stdio or stdlib here? Seems like a waste to me.

No, but it's a good chance to introduce the new C-style headers. Anyway, do you think explaining why they aren't needed would do any good at this point? ;)

That's quite obvious.

help please and thanks again

I suggest you pick up a copy of C Programming Language (2nd edition), by K&R. In the meantime, read this:

Hi there,
In my opinion, your code is beyond repair. You don't need help with your code, you need someone to teach you the basics of programming.
If you post what it is that you want your program to do, maybe we can help you.
