Increments or decrements the iterator.
Let inner_
be the underlying iterator and Base
be the exposition-only member type.
Equivalent to:
++inner_; return *this;
++*this;
auto tmp = *this; ++*this; return tmp;
--inner_; return *this;
auto tmp = *this; --*this; return tmp;
inner_ += n; return *this;
inner_ -= n; return *this;
n | - | position relative to current location |
*this
*this
