Answer 1

1. You shouldn't set this->head = v.head. Because the head is simply a pointer. What you need to do is to create a new head and copy the values individually from v.head into your new head. Otherwise you'd have two pointers pointing to the same thing.

2. You then would have to create a temporary Elem pointer that starts with v.head and iterate through the list, copying its values to new Elem pointers into the new copy.

3. See above.
