# std::make_move_iterator

From cppreference.com
< cpp‎ | iterator

Defined in header `<iterator>` |  |

template< class Iterator > std::move_iterator<Iterator> make_move_iterator( const Iterator& i ); |  | (since C++11) (until C++14)
template< class Iterator > std::move_iterator<Iterator> make_move_iterator( Iterator i ); |  | (since C++14)

`make_move_iterator` is a convenience function template that constructs a std::move_iterator for the given iterator `i` with the type deduced from the type of the argument.

### [edit] Parameters

i | - | input iterator to be converted to move iterator

### [edit] Return value

A std::move_iterator which can be used to move from the elements accessed through `i`

### [edit] Possible implementation

    template< class Iterator >
    std::move_iterator<Iterator> make_move_iterator( Iterator i )
    {
        return std::move_iterator<Iterator>(i);
    }

### [edit] Example

Run this code

    #include <iostream>
    #include <list>
    #include <vector>
    #include <string>
    #include <iterator>

    int main()
    {
        std::list<std::string> s{"one", "two", "three"};

        std::vector<std::string> v1(s.begin(), s.end()); // copy

        std::vector<std::string> v2(std::make_move_iterator(s.begin()),
                                    std::make_move_iterator(s.end())); // move

        std::cout << "v1 now holds: ";
        for (auto str : v1)
                std::cout << "\"" << str << "\" ";
        std::cout << "\nv2 now holds: ";
        for (auto str : v2)
                std::cout << "\"" << str << "\" ";
        std::cout << "\noriginal list now holds: ";
        for (auto str : s)
                std::cout << "\"" << str << "\" ";
        std::cout << '\n';
    }

Output:

    v1 now holds: "one" "two" "three"
    v2 now holds: "one" "two" "three"
    original list now holds: "" "" ""
