C++: Tips and Best Practices. Write Perfect Code

The book "C++: Tips and Best Practices" is not another introduction to the syntax of the language. It is a practical guide for those who already write in C++ and want to take their code to the next level: make it more reliable, faster, and easier to maintain.

The author has compiled over 50 specific recommendations based on experience working on large projects. Each tip is accompanied by code examples, analysis of typical mistakes, and an explanation of why a particular approach is considered best in the C++ developer community.

What you will learn:

• How to properly use smart pointers and manage memory without leaks.
• Modern features of C++17 and C++20: std::optional, std::variant, concepts, coroutines.
• Design patterns adapted to C++ realities (RAII, Pimpl, CRTP).
• Optimization techniques: from choosing containers to writing constexpr functions.
• How to write safe multithreaded code with std::async, std::jthread, and locks.
• Rules for naming, structuring, and documenting code for teamwork.
• Working with exceptions: when to use them and when to avoid them.
• Testing: unit tests, mocks, integration testing in C++.

Who this book is for:

• C++ developers with 1+ year of experience who want to systematize their knowledge.
• Programmers transitioning from C to C++ or from other languages (Java, C#).
• Team leads and architects responsible for codebase quality.

The book is not overloaded with theory — the focus is on practical examples and ready-made recipes. You will be able to immediately apply the tips in your projects. Special attention is paid to performance: real benchmarks are analyzed, and different approaches to solving the same problem are compared.

After reading, you will learn to write code that not only works but is also easy to read, test, and scale. This is a must-have for anyone seriously involved in C++ development.
