Design Patterns for Embedded Systems in C

可以回答这个问题。嵌入式系统中的设计模式可以帮助开发人员更好地组织和管理代码，提高代码的可重用性和可维护性。常见的设计模式包括单例模式、工厂模式、观察者模式等。在 C 语言中，可以使用结构体、函数指针等语言特性来实现这些设计模式。

23 design patterns in C code

Here are 23 popular design patterns in C programming language:

1. Singleton pattern: restricts a class to have only one instance, while providing a global access point to this instance.

2. Factory pattern: creates objects without specifying the exact class of object that will be created.

3. Abstract Factory pattern: provides an interface for creating families of related or dependent objects without specifying their concrete classes.

4. Builder pattern: separates the construction of a complex object from its representation, allowing the same construction process to create various representations.

5. Prototype pattern: creates new objects by cloning an existing object.

6. Adapter pattern: converts the interface of a class into another interface that clients expect.

7. Bridge pattern: decouples an abstraction from its implementation so that the two can vary independently.

8. Filter pattern: provides a way to filter objects using different criteria.

9. Composite pattern: composes objects into tree structures to represent part-whole hierarchies.

10. Decorator pattern: adds behavior to objects dynamically by wrapping them in an object of a decorator class.

11. Facade pattern: provides a simplified interface to a large body of code.

12. Flyweight pattern: conserves memory by sharing data that can be shared among multiple objects.

13. Proxy pattern: provides a placeholder object that controls access to the original object.

14. Chain of Responsibility pattern: passes a request sequentially along a dynamic chain of receivers until one of them handles it.

15. Command pattern: creates objects that encapsulate actions and parameters.

16. Interpreter pattern: provides a way to evaluate language grammar or expression.

17. Iterator pattern: accesses the elements of an object sequentially without exposing its underlying representation.

18. Mediator pattern: allows loose coupling between classes by being the only class that has detailed knowledge of their methods.

19. Memento pattern: captures and externalizes an object's internal state so that the object can be restored to this state later.

20. Observer pattern: establishes a one-to-many relationship between objects, where one object is the subject and the others are observers.

21. State pattern: allows an object to alter its behavior when its internal state changes.

22. Strategy pattern: defines a family of algorithms, encapsulates each one, and makes them interchangeable.

23. Template Method pattern: defines the skeleton of an algorithm in a method, deferring some steps to subclasses.

These patterns can help you write maintainable, reusable, and scalable code in C. However, they are just guidelines, and it's up to the programmer to decide when and how to apply them in specific situations.
