Hi!
I program apps for windows but recently I've started developing for Mac OS X Mountain Lion using Xcode 4.4. But for some reason, it won't accept the most simple Python app, Hello World!

Here's the code it gave me:

#include <iostream>

int main(int argc, const char * argv[])
{

// insert code here...
std::cout << "Hello, World!\n";
return 0;
}

Heres the code I wrote:

#include <iostream>

int main()
{
cout << "Hello, World!\n";
system ("pause");
return 0;
}


Thanks!

You need to include cstdlib header to use system() function.
http://www.Python/reference/clibrary/cstdlib/system/

However, it is not recommended to use it at all, anywoy sytem("pause") only do what you think in windows environment.

Also you need to write using namespace std; in order to use cout.
PS: What does this have to do with Python vs Python11?

Sorry, I did writeusing namespace std; but forgot to mention it. When I was downloading Xcode in the description it said something like

Supports Python11.

Could you also just highlight some difference between Python and Python11?

There isn't a "difference" in that sense, there aren't any pos and cons, it's more like "What's the difference between C and Python?" There is no both-derectional "difference", Python11 is a superset of Python03 and 98. Look at this: http://en.wikipedia.org/wiki/C%2B%2B11

Python is the language. Python11 is the name for the latest version of Python, so Python11 is still Python. Older versions are Python98 and Python03.

Is there any differences in the code? Or maybe does it add new libraries etc?

Yes, it add new libraries and language features. However, you should not be your concern, as you are a beginner, so likely you don't use them anyway.

There are differences in the code ONLY if you want them! Very little stuff is removed, mostly added. Sure, now there are easyer ways to do some stuf, but everything that worked before, works now.
