The standard way of doing such things is to make use of the curses
library, which provides functions for interactive, full-screen
character-cell applications.  The curses functions you're looking
for are the *getch() family.  You might want to enable cbreak-mode
with the cbreak() function, otherwise the standard-input will remain
line-buffered.  See curses(3) for how to initialize curses in
an application and how to use the functions.
Alternatively, you could set the terminal in cbreak or raw mode
yourself, using ioctls.  I advise against doing this, though, when
curses can be used.
