Design Patterns in C++: A Modern Approach

The book "Design Patterns in C++" is a comprehensive practical guide that will help you master classic and modern design patterns in the context of the C++ language. Unlike abstract theoretical manuals, this book focuses on real code examples, C++17/20 idioms, and industry best practices.

What this book is about

The edition covers all 23 classic GoF (Gang of Four) patterns, as well as additional modern patterns such as CRTP (Curiously Recurring Template Pattern), Pimpl, RAII, Type Erasure, and Policy-Based Design. Each pattern is examined using a consistent structure:

• Motivation and Problem — when and why to apply the pattern.
• Structure and Participants — class diagrams and UML.
• Implementation in C++ — ready-to-use code with comments.
• Common Mistakes — how to avoid antipatterns.
• Modern Alternatives — using STL, lambdas, move semantics.

Who this book is for

• C++ developers with at least 1 year of experience who want to systematize their knowledge.
• Software architects looking for flexible solutions for scalable systems.
• Students and graduates of technical fields studying OOP at an advanced level.
• Programmers transitioning from other languages (Java, C#) to C++.

What you will learn

• How to choose the right pattern for a specific task, rather than blindly copying it.
• How design patterns integrate with modern C++ features: smart pointers, templates, concepts, coroutines.
• How to avoid unnecessary complexity and "overengineering" when implementing patterns.
• How to combine multiple patterns in a single system (e.g., Factory + Strategy + Observer).
• Real-world cases from the gaming industry, financial sector, and embedded systems.

The book is written in a lively, accessible style with an emphasis on practice. All code examples are available for download and have been tested under GCC, Clang, and MSVC. After reading, you will be able to design application architectures that are easy to maintain, extend, and test — exactly what distinguishes a professional from a beginner.

"Design Patterns in C++" is not just a reference book, but a desktop companion for anyone who writes C++ seriously.
