I have posted a question about the C++ hello world source code on...

http://www.wikicode.frihost.net/index.php?title=Talk:C_Plus_Plus:Hello_world

Would someone take the time to answer? If you would like, you may simply answer directly on the wiki.

Very good code, thank you very much for your sharing .

main() function should (?) return value.
Code:

#include <iostream.h>
#include <stdio.h>

void main() {
   cout << "Hello World!\nPress ENTER to continue..." << endl;
   getchar ();
        return 0;
}

The main-function should indeed have a return-value. And the way headers are included is the c-way, not the c++way.
But check my respons at the discussion for more information

The main function must return an int value.
Also it must be declared as int instead of void.
Code:

int main() {
    // insert your code here
    return 0;
}

Actually you only return a int if it is int main.And you need to put cin.get(); or something like that to keep the window from closing.

I am not sure what is your question, but here is the actual C++ code for Hello World program:

Code:

#include <iostream.h>

int main()
{
   cout << "Hello World!\n";
   cout << "Press ENTER to continue..." << endl;
   getch ();
   
   return 0;
}

Whats getch(); for? I don't think its required cause I don't need that.
BlackSkad
The getch(); isn't required, but if you leave it, the black screen will pop-up for less the a second and will disappear again. In this way, the window remains open.
You can also achieve this by using 'system("PAUSE");' from the c-lib stdlib (You don't have to cout the sentence "Press blabla..." by using this).

Free c++ compiler
The second link is a good one, I tried it myself for a while, but I stopped learning c++ at the moment. I'm thinking in java now Smile
See it yourself and maybe check some other links...
