Increments or decrements the iterator.

Let inner_ be the underlying iterator and Base be the exposition-only member type.

Equivalent to:

1) ++inner_; return *this;

2) auto tmp = *this; ++*this; return tmp;

3) --inner_; return *this;

4) auto tmp = *this; --*this; return tmp;

5) inner_ += n; return *this;

6) inner_ -= n; return *this;

position relative to current location

1,3,5,6) *this

2,4) a copy of *this that was made before the change
