On a scale from 0 to 1

How based are your arrays?

0 is the null pointer.

Nope. Integer literal 0 can be casted to a pointer type, producing a NULL pointer. DA STANDAH says nothing about the actual representation of a NULL pointer, what it actually "is".

In fact if I remember correctly it doesn't even say anything about converting a non-literal zero (that is, a 0 value of a variable) to a pointer, at least not explicitly. By the way, figuring if DA STANDAH nevertheless implicitly guarantees that you can do that (via interaction with other rules) would be a good problem for an aspiring C Standard Lawyer to cut xir teeth on.
