Best Practices for C++ Programming
🔧 Use the Standard Library Wisely
Leverage STL containers (e.g., std::vector, std::map) and algorithms to avoid reinventing the wheel. Always prefer std::string over C-style strings for safer memory management.
🧠 Adopt Smart Pointers
Replace raw pointers with std::unique_ptr and std::shared_ptr to automate memory deallocation and prevent leaks.
📜 Follow RAII (Resource Acquisition Is Initialization)
Bind resource management to object lifetimes. Ensure resources are initialized in constructors and released in destructors.
💡 Consistent Naming Conventions
Use snake_case for variables and PascalCase for classes. Avoid abbreviations that reduce readability.
🔍 Write Clear Code Comments
Document complex logic and clarify intent. Avoid redundant comments that merely restate code.
🚫 Avoid Global Variables
Minimize use of global state to reduce coupling and improve testability. Prefer dependency injection or singletons when necessary.
🚀 Optimize Performance Strategically
Use const and constexpr to enable compiler optimizations. Profile code before making performance tweaks.
📦 Modularize Code
Break projects into small, focused classes and functions. Use header files for declarations and implementation files for definitions.
📌 Follow Design Principles
Apply SOLID principles (Single Responsibility, Open-Closed, etc.) to create scalable and maintainable systems.
🔧 Use Version Control
Always commit changes to a repository like GitHub. Write meaningful commit messages and use branches for feature development.
