Yeah, fair enough. To my mind I guess I don’t think of array indexes as an example of actual zero based numbering, simply a quirk of how pointers work. I don’t see why one starting from zero has anything to do with the other starting from zero. They’re separate things in my head. Interestingly, the article you linked does mention this argument:

Referencing memory by an address and an offset is represented directly in computer hardware on virtually all computer architectures, so this design detail in C makes compilation easier, at the cost of some human factors. In this context using “zeroth” as an ordinal is not strictly correct, but a widespread habit in this profession.

That said, I suppose I still use normal one-based numbering because that’s how I’m used to everything else working.
