| Defined in header | | | | ------------------------------------------------------------------------------------------------------------------------------------------------------------- | | --------------------------------------------------- | | template< class Iter > move_iterator<Iter> operator+ ( typename move_iterator<Iter>::difference_type n, const move_iterator<Iter>& it ); | | (since C++11) (constexpr since C++17) (until C++20) | | template< class Iter > constexpr move_iterator<Iter> operator+ ( std::iter_difference_t<Iter> n, const move_iterator<Iter>& it ); | | (since C++20) |
Returns the iterator it incremented by n.
| This overload participates in overload resolution only if it.base() + n is well-formed and has type Iter. | (since C++20) |

[edit] Parameters
