Using C++ Language. Implement an ordered linked list, 'OrderedLinkList' class using templates, that has data for students (Name, student ID , CGPA), and the data is sorted in the list as per the student IDs. The class should have the following functions:

- Initialize the list

- Determine whether the list is empty

- Print the list

- Find the length of the list

- Destroy the list

- Retrieve the info contained in the first node

- Retrieve the info contained in the last node

- Search the list for a given item

- Insert an item in the list (make sure that the items are added to the list in a sorted manner)

- Delete an item from the list

- Make a copy of the linked list

- Implement the assignment operator (=)

- Calculate the average CGPA of all students in the list
