I think nearly every C programmer has gone through the phase of Oooh I'll write my own string library! Sure, that works. Except you have to call system libraries and all kinds of other external functions all of which naturally assume the conventional char arrays. So you spend a bunch of time converting back and forth until eventually realizing it's silly, just learn the convention and go with it.
