C++ powers operating systems, game engines, browsers, databases, embedded devices, financial systems, scientific software, and many of the world’s most performance-critical applications. Yet modern C++ is dramatically different from the language many programmers learned years ago.
With the arrival of C++20 and C++23, the language gained powerful new capabilities including concepts, ranges, modules, coroutines, improved constexpr support, std::expected, std::print, and many other modern abstractions. At the same time, C++ remains a systems programming language where ownership, lifetimes, memory layout, and abstraction costs still matter deeply.
Learning C++: A Deep Guide to Modern C++20/23 is a comprehensive and practice-driven guide designed to help readers build a correct and lasting understanding of the language.
Rather than treating C++ as a disconnected collection of syntax rules, this book explains the deeper ideas behind modern C++ design:
- zero-cost abstractions,
- RAII and ownership,
- value semantics,
- compile-time programming,
- generic design,
- performance-oriented engineering,
- and safe abstraction boundaries.
The book begins with the foundations of the language and progressively moves toward advanced topics such as move semantics, templates, concepts, ranges, concurrency, modules, performance analysis, and interoperability with C.
Every chapter emphasizes conceptual clarity, complete runnable examples, and detailed explanations of how the language behaves internally. Error cases, undefined behavior, ownership mistakes, and lifetime problems are treated as essential learning material rather than side notes.
Whether you are transitioning from C, returning from older C++ styles, or learning modern C++ for professional systems development, this book provides the depth and structure needed to understand the language beyond surface-level syntax.
