I thought it was the other way around, a pointer is just an address to
some (a single) memory location which can be part of an array, I'd
not consider int ii to be an array even though int *pp = &ii,
-- but who cares.

But there is a real differnce between
int arr[10];
and
int *pp = calloc(10, sizeof(int));
as pp can be assigned to, but not arr, i.e. pp = malloc() works
but not arr = malloc().
