Creational Design Patterns in Modern C++ - Singleton Versus Monostate

The video tutorial explains the differences between the Singleton and Mono State design patterns. Singleton enforces a single instance through structure, using a private constructor and static instance method, supporting lazy instantiation. Mono State, however, enforces singularity through behavior, sharing state across instances without lazy instantiation. Singleton allows subclassing and can be modified to support multiple instances, known as Multiton. Mono State uses static attributes, making it harder to convert existing classes. Understanding these differences helps in choosing the appropriate pattern for specific use cases.
