The C++ std copy template is implemented this way: template Iterator2 copy (Iterator1 start, Iterator1 stop, Iterator2 result) { while (start != stop) { *result = *start3; ++start; ++result; %3D return result; Suppose that we want to use copy this way: Container c1; Container c2; copy (c1.begin(), c1.end(), c2.begin()); Which of the following conditions is required if the copy is to work properly? O Iterator1 must have a copy constructor Container must provide both const and non-const iterators Element must have a copy constructor Element must have an assignment operator c2 must already contain at least as many elements as c1
