Hi, I am trying to learn c++ from a book called c++ primer. I am using vs .net 7.1
This will sound like a silly question but has c++ changed heaps in this compiler?
When i start a new win32 console app this is what it looks like

#include "stdafx.h"

int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}


_tmain?? whats that?

Any way, i tried putting this line above return

cout<<"hello world";

and i get this error

error C2065: 'cout' : undeclared identifier

Is my book way out of date or are there only minor changes or is it something else?

Thanks heaps for any info
