Stay Updated
- C++ is an evolving language. Stay updated with the latest standards (C++11, C++14, C++17, C++20) and best practices.
-
Avoid Global Variables
- Limit the use of global variables as they can lead to tight coupling and make your code harder to debug and maintain.
-
Document Your Code
- Use tools like Doxygen to generate documentation from your code comments. This helps maintain a clear understanding of your codebase.
-
Use Exceptions Wisely
- Use exceptions for error handling rather than error codes. Make sure to catch exceptions by reference to avoid slicing.
-
Understand Object 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.
-
Optimize After Measuring
- Don’t prematurely optimize your code. Write clear code first, then profile it to find bottlenecks before making performance improvements.
-
Be Careful with Memory Management
- Always match
newwithdeleteandnew[]withdelete[]. Use smart pointers to simplify this and avoid common pitfalls
- Always match
-
Follow Consistent Coding Standards
- Adopt a coding style guide (like Google C++ Style Guide) and be consistent with naming conventions, formatting, and structure.
-
Comment Wisely
- 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.
