Master 4 Key Design Patterns
Clean architecture starts here. Command · Observer · Singleton · Strategy — battle-tested C++ solutions for real-world software design.
Focus patterns
Command
Encapsulate a request as an object, allowing parameterization, queuing, logging, and undoable operations. Decouples sender from receiver.
Observer
Define a one-to-many dependency so that when one object changes state, all dependents are notified automatically. Perfect for event-driven systems.
Singleton
Ensure a class has only one instance and provide a global point of access to it. Thread-safe variants, lazy initialization, resource control.
Strategy
Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients.
