You should indeed be including <iostream> rather than <iostream.h>. Then,
be aware that most (all?) of the standard headers - i.e. the ones without
the ".h" - put everything in the namespace "std", so e.g. you have to
reference cout as std::cout.
BTW cout is a standard library class (it incorporates the functionality
of stdout and much more), so you won't find a man page for it, but you
will certainly find it in your C++ textbook, probably under I/O stream
classes or somesuch. Read up on namespaces too.
It's a steep learning curve, but hands-on is a good approach :)
Good luck,
