Uh,  no.

Eight bits can represent 256 different values,  but since one of them is zero,  the highest value that can be represented is 255,  not 256.  You add 1 to 255 and _that_ wraps around to zero...

There are 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors.
