The compiler might delete that code if it has not side effects. 5. You dereference the pointer too, not only incrementing it. That dereference will give you the value pointed to by the old pointer (before the increment) but you don't use that value, leading to the warning. Simple solution? Don't use the dereference operator *. In other words, *p++ parses as *(p++).
