Imagine you're refactoring a legacy C++ codebase. It heavily uses friend functions, leading to a maintenance burden and difficult-to-follow code. What strategy might you adopt to improve encapsulation and maintainability without sacrificing performance?
- Use inheritance exclusively.
- Encapsulate the required data and use getter/setter functions.
- Make all data public to avoid using friend functions.
- Refactor to use forward declarations.
While getter and setter methods might introduce a slight overhead, modern compilers can inline these functions to ensure minimal performance impact. By encapsulating data, you enhance the maintainability and structure of the code.
