Architecture of C++ Applications. Patterns, Idioms, and Best Practices

The book "Architecture of C++ Applications" is a practical guide to designing and developing complex software systems in C++. It is intended for developers who already have basic experience programming in C++ and want to move to the next level — learning to create scalable, maintainable, and high-performance applications.

Unlike many textbooks that focus on syntax and basic language constructs, this book is dedicated specifically to architectural decisions. You will learn how to properly organize code so that it is flexible, testable, and resilient to changing requirements.

What you will learn from the book:

• SOLID principles in C++ — how to apply them in practice, avoiding common mistakes.
• Design patterns — from classic GoF to modern C++ idioms (RAII, PIMPL, CRTP, NVI).
• Memory management — smart pointers, custom allocators, resource management strategies.
• Multithreading and concurrency — designing thread-safe components, using std::thread, std::async, std::atomic.
• Component architecture — modularity, loose coupling, dependency inversion.
• Performance — caching, compile-time optimization, profiling.
• Testing — unit tests, mocks, dependency injection for C++.

Who this book is for:

• C++ developers wanting to systematize their knowledge of architecture.
• Team leads and architects seeking practical recipes for real-world projects.
• Senior students preparing to work on large codebases.

The author of the book is an experienced developer with 15 years of experience, who has participated in creating high-load financial systems and game engines. All code examples have been tested on C++17/20 compilers and are available for download.

This book will become your desktop reference when designing new applications and refactoring existing ones. You will learn not just to write code that works, but to create an architecture that lives and evolves with the project.

The book "Architecture of C++ Applications" is an investment in your professional future. After reading it, you will look at code differently: seeing not just lines, but a cohesive system where every decision has a rationale.
