Converting a character to hex?

[M3GAPL3X]

Hi all,

I was doing some sample problems in my C++ book and I stumbled across this problem. It bascially wants any character converted to ascii. To my knowledge, there is no C++ function that does, so I probably need to make my own function. If anyone can give me some hints on solving this problem or creating a function, it would be greatly appreciated!

i'll assume you mean 'converted to hex', not ascii (unless you're on a bcd machine, in which case you're beyond help).

well, that's pretty straightforward. you know each 8bit char can be represented as 2 hex characters. without writing the code for you, here are the steps you need:

split your char into "high" and "low" halves. each of these is one hex character (4 bits).
find a way to get the corresponding hexadecimal character of a 4 bit value.
