How to improve code readability and maintainability in C++ class design?

Answer: The following strategies can be used to improve the readability and maintainability of C++ class design: clear and concise naming conventions, clear class structure and access modifiers, documentation comments, design patterns, single responsibility principle

Improve the readability and maintainability of C++ class design

Good class design is the basis for creating readable and maintainable code. Here are some strategies to help you improve the quality of your C++ class design:

1. Use clear and concise naming conventions

Naming conventions help keep your code consistent and predictable. Use meaningful and descriptive names and avoid abbreviations or ambiguous names. For example, a class representing a timestamp could be named TimeStamp instead of ts.

2. Follow a clear class structure

Group related members together, such as data members, methods, and constructors. Use access modifiers such as public, private, protected to control the visibility of members. This helps organize your code and prevents external code from accessing undocumented members.

3. Write documentation comments

Documentation comments (such as Doxygen comments) provide detailed information about classes, members, and methods. This helps other developers understand the purpose and usage of the code.

4. Use design patterns

Design patterns provide proven code structures to solve common programming problems. Using design patterns can reduce code duplication and complexity, thereby improving maintainability.

5. Adhere to the single responsibility principle

Each class should be responsible for a clearly defined goal. Avoid creating "god classes", i.e. classes that take on too many responsibilities. This helps improve code readability and maintainability.

Practical Case

Consider a class that represents inventory items:

class InventoryItem {
public:
    // 构造函数
    InventoryItem(const std::string& name, int quantity);

    // 获取商品名称
    const std::string& getName() const;

    // 获取商品数量
    int getQuantity() const;

    // 设置商品数量
    void setQuantity(int quantity);

private:
    std::string name_;
    int quantity_;
};

This class follows a clear naming convention, has clearly defined responsibilities, and it uses access modifiers to restrict Visibility of members. This improves code readability and maintainability.
