On UNIXes you'd put the standard input stream into non-canonical mode (using the flag ICANON if I recall correctly) with tcgetattr() and tcsetattr(). Once that's done you need to deal with each character hit and display characters as appropriate.

On other systems you'll probably use orher approaches (e.g., kbhit() if I recall correctly).
