Behavioral Design Patterns in C++ - Lamp - V (Factory)

The video tutorial addresses the issue of tight coupling between state classes in the Lam project. It suggests using a factory method to reduce dependencies caused by the 'new' operator. The tutorial then explores implementing the Singleton pattern to manage state instances efficiently, reducing repetitive creation and destruction. It also discusses the potential use of the Flyweight pattern if state classes carry intrinsic and extrinsic states. The tutorial concludes by recommending the appropriate design pattern based on the application's requirements.

Explain how the factory can behave like a registry of singletons.
