Clean Code in C++. A Practical Guide to Writing Reliable and Maintainable Code

The book "Clean Code in C++" is not just a collection of syntactic rules. It is a comprehensive practical guide that will teach you how to write code that is easy to read, maintain, and extend. If you are familiar with the basics of C++ (classes, inheritance, templates) but feel that your code is becoming "dirty," breaks with the slightest changes, and causes headaches for your colleagues — this book is for you.

The author, Alexey Sokolov, a senior developer with 12 years of experience, has gathered in this book the best practices proven in real commercial projects. You will learn how to apply SOLID principles in the context of C++17/20, how to properly use smart pointers and RAII for resource management, and how to avoid classic language pitfalls (undefined behavior, memory leaks, copy issues).

What you will learn from the book:

• How to write self-documenting code: choose proper names, format, and comment without fanaticism.
• The YAGNI, KISS, and DRY principles in the context of C++ — how to avoid over-engineering and complicating the architecture.
• Refactoring legacy code without risk: step-by-step techniques for extracting classes, replacing macros with constexpr, and eliminating copy-paste.
• Unit testing using Google Test and Catch2: how to write tests that truly protect against regressions.
• Working with exceptions: when to use them, and when it's better to return std::optional or std::expected.
• Modern design patterns: Visitor, Strategy, Pimpl, CRTP — with examples adapted for C++20.
• Performance optimization without sacrificing readability: profiling, move semantics, SSO, allocators.

Who this book is for:

• Junior developers (1-2 years of experience) — to form good habits from the start.
• Middle developers — to systematize knowledge and learn refactoring.
• Team leads and architects — as a reference for code review and coding standards.

In each chapter, you will find not only theory but also specific examples of "bad" and "good" code, as well as exercises for reinforcement. The book is written in a lively style, without excessive academicism, and is suitable even for those just starting their journey in professional C++ development.

After reading, you will be able to create projects that any new team member can understand, and adding new functionality will no longer be a "game of Russian roulette." Make your code clean — and it will reward you with stability and the respect of your colleagues.
