difference between stdio.h and iostream.h?

i used to iostream for output with c++, but I have been noticing stdio.h more common for output since iv started linux? is stdio more for C and iostream made for c++? or is it just a preference?

A: Yes

Q: and iostream made for c++?
A: Yes

Q: or is it just a preference?
A: Yes

ALSO:
Using "printf()" in C++ is sometimes frowned upon...
... but you simply *can't* use "cout" in C.

'Hope that helps

It is not just a preference -- they refer to entirely different things:

Code:

# include <sdtio.h>



...



printf("There are %d bottles of beer on the wall\n",total);

Versus:

Code:

#include <oiostream>



...



std.cout << "There are " << total << " bottles of beer on the wall" << std.endl;

Completely different design and intention. By the way, in your programs don't mix the two I/O styles shown above -- use one or the other exclusively. Mixing them causes endless synchronization difficulties.
