>how do you know which librarys are C librarys which are C++ and which are non standard and still require the .h?
It takes a while to learn. Ideally get a good book (see the sticky at the top of the forum for recommendations). Accelerated C++ is supposed to be good.

One other note: most nonstandard headers need a .h. Examples would be:

Code:

<windows.h>    //For Windows programming
<conio.h>      //For clrscr(), gotoxy()
<sockets.h>    //For sockets (network) programming
<signal.h>
