Binary array to printable hex string in C

If only I knew the purpose of my life, I would see the justification in me doing what I do. What the heck, I could'n care less about every random occerance to have a purpose else Gauss and Laplace wouldn't have been legends. As for me I am a mere mortal who among other things, enjoy's killing bugs and I guess my passionate animosity towards bugs is what helps me in doing whatever I do somewhere in the NorthWest. (Don't you guys make up any ideas about too many bugs in anything that comes out of NorthWest). Just be aware, it could be worse, if not better .
And I live my life happily there after.
