Emulating Constants w/ Individual Characters
You say that title doesn't make sense? What? Oh, okay, I'll explain...
In printf(), you can print a character by feeding it a hexidecimal number, as follows:
This would produce the character a. Now, the complicated part. How would I emulate that hex constant if I had the first digit in one character, and the second in another character? Do I need to actively convert from the hex to decimal and feed that to the character? I'm perfectly able to do that conversion, I'm just using this as a learning experience.
Thanks for any light you may be able to shed on the subject.
