You don't mention which machine or compiler you are using, but the standard
libraries for a few diffenent DOS C compilers contain the function getch().
This function will do exactly what you want it to do.  If your library does
not include getch(), you may be able to do it with the systems DOS interface
(i.e. bdos() or intdos()).

Unix Sys 5 has a library function called getpass() that will prompt the user
with a string (of your choosing), and get the typed response without echoing
the characters to the screen.
