C++ Best Practices

Table of Contents Introduction About Best Practices Use the Tools: Automated Tests Use the Tools: Continuous Builds Use the Tools: Compiler Warnings Exercise: Use the Tools: Static Analysis Use the Tools: Sanitizers Slow Down C++ Is Not Magic C++ Is Not Object-Oriented Learn Another Language const Everything That's Not constexpr constexpr Everything Known at Compile Time Prefer auto In Many Cases. Prefer ranged-for Loop Syntax Over Old Loops Use auto in ranged for loops Prefer Algorithms Over Loops Don't Be Afraid of Templates Don't Copy and Paste Code Follow the Rule of 0 If You Must Do Manual Resource Management, Follow the Rule of 5 Don't Invoke Undefined Behavior Never Test for this To Be nullptr, It's UB Never Test for A Reference To Be nullptr, It's UB Avoid default In switch Statements Prefer Scoped enums Prefer if constexpr over SFINAE Constrain Your Template Parameters With Concepts (C++20) De-template-ize Your Generic Code Use Lippincott Functions Be Afraid of Global State Make your interfaces hard to use wrong. Consider If Using the API Wrong Invokes Undefined Behavior Use [[nodiscard]] Liberally Use Stronger Types Don't return raw pointers Prefer Stack Over Heap No More new! Know Your Containers Avoid std::bind and std::function Skip C++11 Don't Use initializer_list For Non-Trivial Types Use the Tools: Build Generators Use the Tools: Package Managers Improving Build Time Use the Tools: Multiple Compilers Fuzzing and Mutating Continue Your C++ Education Thank You Bonus: Understand The Lambda
