What he's talking about is pointer arithmetic. In assembly you have to "know" what is being pointed at such that you can access an element in an array or a component of a composite type, for example. The computer only knows about bytes. In C you can just do stuff like `(p + 6)->t` and the compiler knows how many bytes "+6" is because it knows what `p` is pointing at. |
