C++ operator precedence

Question

Lets say we have an iterator (iter) over a list of pointers to memory assigned to heap space, if I do that

delete (*iter++)

am I right that the precedence is first dereference iterator to get memory address then free the space and then increment the iterator to free the next element ?

Answer 1

Although ++ has higher precedence than *, the side effects of post-increment ++ are applied after the dereference operator * has used the iterator's value. That is the behavior of the post-increment, or suffix ++, (as opposed to the pre-increment, or prefix ++). This rule applies to iterators as well as the "plain" pointers.
