In ANSI C, there is no binary representation available. Watcom C
I believe has an extention to allow you to use something like:


But ANSI does not allow this. There is a way of implementing it
in a portable way by creating a header file containing #define's
of all binary values like this:

#define b00000000 0x00
#define b00000001 0x01
#define b00000010 0x02
#define b00000011 0x03
#define b11111111 0xFF

That only accounts for 8 bit binary numbers however. You're
better off sticking to hex notation wherever possible, and
perhaps putting binary numbers in comments behind the hex
