This might work to a limited extent, but one begs to ask the question,
have you set your mode to C++? A quick meta-x c++-mode will probably solve
your problems. This is covered in the Gnu Emacs manual, btw. Not only does
the mode give you proper indentation, but also proper highlighting of
code, electric this and that... etc.

Yeah, but the person said he could tab if he set the tab stops. My guess
is he's in scratch editing in fundemental.
