| template< class InputIt, class OutputIt > OutputIt move( InputIt first, InputIt last, OutputIt d_first ); |
（C++11 起） | |
[first, last)中的元素，到另一个范围开始于d_first。此操作后，移离范围中的元素将包含有效的数值适当类型的，但不一定是相同的值前移到.[first, last), to another range beginning at d_first. After this operation the elements in the moved-from range will still contain valid values of the appropriate type, but not necessarily the same values as before the move.You can help to correct and verify the translation.
