- C++ is an evolving language. Stay updated with the latest standards (C++11, C++14, C++17, C++20) and best practices.
-
- Limit the use of global variables as they can lead to tight coupling and make your code harder to debug and maintain.
-
- Use tools like Doxygen to generate documentation from your code comments. This helps maintain a clear understanding of your codebase.
-
- Use exceptions for error handling rather than error codes. Make sure to catch exceptions by reference to avoid slicing.
-
- Be aware of object slicing when using base class pointers to refer to derived class objects. Use pointers or references to avoid slicing issues.
-
- Don’t prematurely optimize your code. Write clear code first, then profile it to find bottlenecks before making performance improvements.
-
- Always match
new with delete and new[] with delete[]. Use smart pointers to simplify this and avoid common pitfalls
-
- Adopt a coding style guide (like Google C++ Style Guide) and be consistent with naming conventions, formatting, and structure.
-
- Write clear and concise comments, but avoid redundant comments. Code should be self-explanatory, so use comments to explain why something is done, not what is being done.
-
- Use testing frameworks (like Google Test) to write unit tests for your code. This helps ensure correctness and allows for easier refactoring.
