Increments or decrements the iterator. Inverse operations are applied to the underlying operator because of the reverse order.

1-2) Pre-increments or pre-decrements by one respectively.

3-4) Post-increments or post-decrements by one respectively.

5-6) Returns an iterator which is advanced by n or -n positions respectively.

7-8) Advances the iterator by n or -n positions respectively.

Return value

1-2) *this

3-4) a copy of *this that was made before the change

5-6) reverse_iterator(base()-n) or reverse_iterator(base()+n) respectively.

7-8) *this
