Difference between <iostream> and <iostream.h>

[Shahmeer]

Hi everyone,
I just wanted to ask what the difference between these two is:

#include <iostream>

and

#include <iostream.h>

I am just a bit confused.

<iostream.h> is an old non-standard header that some old compilers support. It puts everything in the global namespace instead of the std namespace like <iostream> does.

<iostream> is the correct one. If the compiler doesn't have it you should consider getting a more up to date compiler.

[Shahmeer]

Yeah, I have Visual Studio 2012 RC and so this doesn't support <iostream.h>?
But anyway, I shouldn't use it. Right?

[MrHutch]

Yep, avoid it. Use #include <iostream> .

Yeah, thanks!
