Behavioral Design Patterns in C++ - Basic Implementation-Iterator

The video tutorial covers the implementation of the Iterator and Aggregate classes, followed by the creation of concrete versions of these classes. It demonstrates how to handle circular dependencies between header files and shows how to use these classes in a main function. The tutorial concludes with a summary and a preview of the next lecture on the iterator pattern.

What issue arises from the header files concrete aggregate and concrete iterator?

How does the client interact with the base classes for polymorphic iteration?

What will be demonstrated in the next lecture regarding the iterator pattern?
