You might be getting a warning for using old C headers in C++...

This should give you 0 warnings:

#include <iostream>int main(void){	std::cout << "Hello, world!\n";	std::cin.get(); /* keeps the console open until you hit a key */}

Well he _is_ using a C++ compiler and stated he was using C++ in the OP, so I just assumed so. C code is compiled with gcc, not g++.

And main() always return int, never void anyway.

That isn't the whole error message. It continues on the next line, or something.

For heaven's sake, stick with Python. If you're running any vaguely recent version of Windows, and this direct link straight from python.org doesn't result in a perfectly straightforward install, then something is seriously odd about your system...

you're missing the return type there, shouldn't the real answer be:

#include <stdio.h>int main(int argc, char **argv){   printf("Hello World!\n");   return 0;}

In C, you should have return 0 at the end of main. However in C++, if the main function returns nothing, a return value of 0 is assumed and the compiler takes care of the rest for you.

Well, there is no return in your function :(

If you read my above post, you will see why there doesn't need to be a return value...

My bad. Just give me the time to read the standard again. Yes, you are right (of course). < joke > Thus, this is valid but bad programming :) < / joke >

Personally, I'd try:

#include <stdio.h>void main(){printf("Hello World\n");return 0;}

Or, in C++,

#include <iostream.h>int main(){cout<<"Hello World\n";return 0;}

In standard C and C++, main() is required to specify an int return type, it is not implied. In C and C++ there is an implicit return 0 at the end of main(). A fully conforming hello world in C++ is:

#include<iostream>#include<ostream>int main(){  std::cout << "Hello World" << std::endl;}

I think this thread has gone astray of being any help to the OP. I really don't think anyone needs to see another hello world program.

I'm not trying to be an ass, its just that the OP's question was answered already and people are arguing over the proper syntax of return statements, streams, input params etc. Starting to look more like a pissing contest, and if the OP wants to post another question they will need to read through all of this crap.
