Increments or decrements the iterator, by applying the corresponding operation on
the underlying iterator.

1-3) Increments by one.
4,5) Decrements by one.
6,7) Advances the iterator by n or -n positions respectively.

Return value¶

1,4,6,7) *this
3,5) A copy of *this that was made before the change
2) (none)
