Increments or decrements the iterator.
Let current_ be the underlying iterator and pos_
1) Equivalent to
++current_;
++pos_;
return
*this;
2) Equivalent to ++current_;
3) Equivalent to
auto tmp =
*this;
++*this;
return tmp;
4) Equivalent to
--current_;
--pos_;
return
*this;
5) Equivalent to
auto tmp =
*this;
--*this;
return tmp;
6) Equivalent to
current_ +
= n; pos_ +
= n;
return
*this;
7) Equivalent to
current_ -
= n; pos_ -
= 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
