Sorry, but there are no such things as "scan codes" in standard C.

Perhaps you should try a newsgroup that relates to your compiler or operating
system support.

You're asking about this in the wrong place. Here,
only ISO standard C is discussed. The C language
defines no concepts of 'keyboards', 'keys' 'scan codes',
or 'ascii codes', or any particular hardware devices
or their operation or behavior. All i/o is abstracted
as 'streams of characters'.

Try consulting support resources for your particular
platform and/or compiler package.

How does one get scan codes of alphabetic keys? getkeycodes Plain scancodes xx (hex) versus keycodes (dec)
0 is an error; for 1-88 (0x01-0x58) scancode equals keycode
