Strategy lets the algorithm vary independently from clients that use it. Strategy Pattern: Defines a family of algorithms, encapsulates each one, and makes them interchangeable. Observer Pattern: Defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. Useful for creating objects with varying implementations. Useful for maintaining a single point of control, such as a configuration manager.įactory Method Pattern: Defines an interface for creating an object but lets subclasses alter the type of objects that will be created.
Singleton Pattern: Ensures a class has only one instance and provides a global point of access to it. Design patterns help you create code that is more modular, flexible, and easier to maintain. They are not specific to a programming language but can be applied to different languages, including C++. Design patterns are recurring solutions to common problems in software design, and they provide a blueprint for writing clean, maintainable, and efficient code.ĭesign patterns are tried-and-tested solutions to common software design problems. Hello, dedicated learners! It's Day 17 of your incredible 100-day C++ learning journey, and today, we're delving into the world of C++ design patterns.
