Web std:: copy template OutputIterator copy (InputIterator first, InputIterator last, OutputIterator result); Copy range of elements Copies the elements in the range [first,last) into the range beginning at result. WebConstructs a back-insert iterator that inserts new elements at the end of x. A back-insert iterator is a special type of output iterator designed to allow algorithms that usually overwrite elements (such as copy) to instead insert new elements automatically at the end of the container.
