String Usage and Architecture

Read this right now and needed to point out an error:

The author says "myarray[2] is really just shorthand for *(myarray+2)". That is not true myarray[2] is the same as *(myarray+sizeof(myarray_element_type)) and that is acctually a huge difference.

Actually im fairly sure that myarray[2] and *(myarray+2) are exactly the same.

No it's not. The element size is implicit in both cases. The only time the element size matters is if you're dealing with raw bytes, such as for memcpy().

myarray[2] is the same as *(myarray+2). Try it with an array of ints and see.

ahh... missed the mulitplication with the index. My bad.

Are you sure that the size is implied? I have done the exact same thing some time ago and i sertainly did not work. But I'll try it again when I get home (at "work" now).

ok... I was wrong. Tested and verified now.
