First, getch() can also read arrow keys and other non-ASCII keys: it 
returns zero, and you then need to call it again, to get the scan code.

An alternative is to use the function getxkey().  This one goes through 
the BIOS, and so recognizes more keys.  Its disadvantage is that BIOS 
doesn't know about national keyboards, so characters that are produced 
using the right ALT key need special translation tables.  The header 
<keys.h> includes symbolic definitions for all the scancodes of non-ASCII 
characters for use with getxkey().
