Sure.

You can use
 #include <iostream>
, although not _all_ standard C++ headers are present at the current
time.

"using namespace std;" works.

As long as you use standard C++, you should have minimal trouble doing
that.  If you use GNU entensions or Microsoft extensions, then you have
to mark them with #ifdef's.

More help on C++ can be gotten by reading the C++ FAQ, the GCC FAQ and
the DJGPP FAQ.
