Behavioral Design Patterns in C++ - Organization - II (Cursor)

The video tutorial explains the concept of a cursor in the iterator pattern, where the cursor holds the state of iteration while the traversal algorithm resides in the aggregate. It covers creating and using a cursor, implementing the iterator pattern, and ensuring data privacy by converting the cursor into a class. The tutorial also highlights limitations, such as difficulty in backward traversal, and hints at future improvements.

How does the implementation of the Cursor class help in hiding data from clients?

What limitation does the current implementation have regarding traversal direction?
