well, i have this .c code... and im trying to convert it to assembly... and i cant seem to figure out where to start... can you guys help me out...

This is the best I can do until you start to post your own realistically attempted code.

Bite sized chunks.
Make your ASCII and integer print functions then test!

Try to rework your functions in C into a simpler form!
You can use an ASCII table

char szHex[] = "0123456789ABCDEF"

or

if digit <= 9
    c = digit + '0'
else
    c = digit + 'A' - 10

Note the difference between '0' 0x30 and 'A' 0x41 is 0x11

if (digit > 9) digit += 0x11      'A'-'0'

c = digit + '0'

or branchless!

c = (10 - digit) >> 15        ;   15 if 16-bit integers
c &= ~0x11
c += '0' + digit

No, no, no! It is not a C question. It is an Assembly question, but the code is far away from being clearly seen as assembly code.

ALWAY write you assembly code in a Higher level language such as (C) not C++ and make it lite weight and clear there first. That's all that needs to be done here first. Rework this C code to be simpler.
