All the \n does is outputs a new line, so rather than the program doing
this:

[someuser@aunixmachine ~] $ ./a.out
Hello world![someuser@aunixmachine ~] $ _

it will put the newline on the end of the string, making it look like this:

[someuser@aunixmachine ~] $ ./a.out
Hello world!
[someuser@aunixmachine ~] $ _

Not sure about it not appearing at all.  I think it would appear when
the program ends, but then again, I may be wrong.

Actually, if you've got root access, you can add the following line to
your /etc/profile, or as above, your ~/.bashrc file:

export PATH="$PATH:."

	Actually, gVim may not be such a bad idea.  It's vi, but has a
graphical frontend with menus, etc.  Emacs, yeah, I've used it, not bad,
but I've become a vim person myself.  Also, there's PICO (a really basic
editor), or Jed (quite a nice tool).

	Nothing wrong with kwrite, it isn't too bad to use.  Basically, use
anything you like, just make sure it spits the file out as plaintext
(nothing like MS Word formatting characters to add to the compiller
messages and mangle your code).
