Array accessing is NOT user pointer/address arithmetic

In C it most definitely is. A[B] is by definition just another way of spelling
*((A)+(B)), which is clearly pointer arithmetic.

Worry about improving performance after it's working.

For many applications performance is part of the definition of working, e.g. hard real-time control.

Unless you are coding 200 Ms /s DSP or a tiny micro controller managing 1MHz signals, performance is the last thing to worry about.

Precisely my point- sometimes you *are* writing high speed DSP code or using tiny embedded processors (or kernel code, or memory management code, or any of a gazillion other areas where pointer arithmetic is useful).
What’s normal in one field isn’t necessarily so in others.
