using c++ write a member function that will delete the first node of a doubly linked list a member function that creates a pointer that points to the first node of a doubly linked list a member function that moves the pointer to the next node of the doubly linked list a member function that moves the pointer to the node before a member function that deletes the node the pointer is pointing to a member function that returns the value of the node the pointers pointing too and a member function that will return the reference of the first node that has the value B. start the search from the pointer.
