Behavioral Design Patterns in C++ - Generic Acycle Visitor - II

The video tutorial discusses optimizing Shape subclasses by removing boilerplate code for dynamic cost and introducing a base class called Visitable using the Curiously Recurring Template Pattern (CRTP). The Visitable class inherits from Shape and overrides the accept method. The tutorial also explains modifying the inheritance hierarchy, where Shape subclasses now inherit from Visitable. The video covers code cleanup, removing unnecessary files, and building the project. The final design structure is explained, highlighting the benefits of no circular dependency and allowing partial visitation.
