Question

C++ programming

design a class to implement a sorted circular linked list. The usual operations on a circular list are:
Initialize the list (to an empty state).
Determine if the list is empty.
Destroy the list.
Print the list.
Find the length of the list.
Search the list for a given item.
Insert an item in the list.
Delete an item from the list.
Copy the list.

Write the definitions of the class circularLinkedList and its member functions (You may assume that the elements of the circular linked list are in ascending order). Also, write a program to test the operations of your circularLinkedList class.

NOTE: The nodes for your list can be defined in either a struct or class. Each node shall store int values.

first
(a) Empty circular list
first
(b) Circular linked list with one node
first
(c) Circular linked list with more than one node
In a circular linked list with more than one node, as in (c) in the Figure above, it is convenient to make the pointer first point to the last node of the list. Then, by using first, you can
access both the first and the last nodes of the list. For example, first points to the last node, and first->link points to the first node.
