copy()

The behavior of this function template is equivalent to:

template<class InputIterator, class OutputIterator>
  OutputIterator copy (InputIterator first, InputIterator last, OutputIterator result)
{
  while (first!=last) {
    *result = *first;
    ++result; ++first;
  }
  return result;
}

Copies the elements in the range [first,last) into the range beginning at result.

The function returns an iterator to the end of the destination range (which points to the element following the last element copied).

Input Iterator to the initial and final positions in a sequence to be copied. The range used is [first,last), which contains all the elements between first and last, including the element pointed by first but not the element pointed by last.
