Increments or decrements the iterator.
Let current_
be the underlying iterator.
1) Equivalent to ++current_; return *this;
2) Equivalent to ++current_;
3) Equivalent to auto tmp = *this; ++*this; return tmp;
4) Equivalent to --current_; return *this;
5) Equivalent to auto tmp = *this; --*this; return tmp;
6) Equivalent to current_ += n; return *this;
7) Equivalent to current_ -= n; return *this;
Parameters
n | - | position relative to current location |
Return value
1,4,6,7) *this
3,5) a copy of *this
that was made before the change
