Question

In the textbook problem from Data Abstraction & Problem Solving with C++: Walls and Mirrors(7th edition), chapter 4, programming problem 6. If I want to build a copy constructor for the DoublyLinkedBag class. How can I do it.

//this is the beginning of the copy constructor

DoublyLinkBag(DoublyLinkBag& aBag){}

Answer 1

Since you have not provided the code for DoubleLinkedBag, I cannot provide the complete implementation of DoublyLinkedBag.

Hence, I am providing a sample implementation of the copy constructor.

DoublyLinkBag(DoublyLinkBag& aBag){

this->data = aBag.data;

this->prev = aBag.prev;

this->next = aBag->next;

}
