In c++ use Doubly-Linked list to write the following classes, define your classes in a header file and implement in a .cpp file. Also include a main.cpp to test your program.

You are going to implement a variant of the standard linked list. the doubly linked list Doubly linked lists are because they enable a backwards and forwards traversal of the list through the addition of more pointers. By increasing the memory cost of the list, it enables a better access since the list does not need to be traversed in only one direction This will consist of implementing two classes: dLL and item dLL The class is described according to the simple UIL diagram below You are going to implement a variant of the standard linked list. the doubly linked list Doubly linked lists are because they enable a backwards and forwards traversal of the list through the addition of more pointers.
