It's not the same as (index + arr). arr is a pointer to the beginning address of a series of particular "types". These types have a specific size in memory. Index increments the pointer by (n * size_of(type)).

arr[index] == arr + (n * size_of(type)) == (n * size_of(type)) + *arr

[SamReidHughes]

He said it's the same as

    *(index + arr)

which is correct.

C pointer arithmetic already accounts for object sizes.

And it's sizeof, not size_of. And

    arr + x

is completely different from

    x + *arr

And it's a series of "values".

I don't know what I was on. Proof positive that sleep depravation does not give me more time to be "productive". Thanks for the correction and apologies for my mistake.
