How do you call your functions?

A) poststupidshit
B) post_stupid_shit
C) PostStupidShit
D) postStupidShit
E) pss lol
etc

I call them like PostStupidShit or XXX_PostStupidShit where XXX is a module's short name.

what is the difference between that and regular C? From my understanding OO concepts are not language dependant so why does objective C exist? I've also never used it and google doesn't work for me. Actually no, I'm just lazy to look it up.
