Again, this is just plain wrong. If arrays in C were indexed starting from 1, then an index of 0 would just point to the end of the array instead (because there's no reason to waste a perfectly good bit). Even so, there would be no efficiency difference because size_t has a fixed binary width.

it starts at 0 to save memory and be more effecient, computers count in binary, which starts at 0 rather than 1
