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) ++*this;
3) auto tmp = *this; ++*this; return tmp;
4) --inner_; return *this;
5) auto tmp = *this; --*this; return tmp;
6) inner_ += n; return *this;
7) inner_ -= n; return *this;

Parameters


n - position relative to current location

Return value


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