You need to re-read the cc (1) manual page. The o flag specifies
the name of the output file.

As per Rick Pettit's note, you need this line:
initscr(); // start curses mode
Note that initscr() has side effects, like moving the cursor to
the top of the screen.
You probably want to get real comfy with the curses documentation.
As an alternative to all this, you may be able to get by with
just printing the bell character, ^G. It doesn't work with all
combinations of shells and terminals and languages and whatnot,
and it's been years since I did any serious C programming, so I
don't remember exactly how it's done there, but I'll often use ^G
when I can get away with it.
