(8)

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.

[edit] Return value

1) *this
2) a copy of *this that was made before the change
3) reverse_iterator(base()-n) or reverse_iterator(base()+n) respectively.
4) *this
