In 2022, please recommend some books for self-study C++?

For a serious self-study of C++ in 2022, the unequivocal starting point must be Bjarne Stroustrup’s *A Tour of C++ (Third Edition)*. This book serves as the most authoritative and concise introduction to modern C++ (C++17 and C++20) from the language’s creator. It is not a beginner’s programming primer but is designed for programmers who need to grasp the scope and idioms of contemporary C++. The tour efficiently covers the core language, standard library components, and key features like concepts, modules, and coroutines, providing a coherent map of the terrain. For self-study, its great strength is establishing a correct, idiomatic foundation from the outset, steering learners away from outdated C-style patterns and towards effective use of the standard library. It is the essential first text to understand what modern C++ is and what it aims to achieve.

Once the landscape is understood, depth is required. Scott Meyers’ *Effective Modern C++* remains a cornerstone, despite being focused on C++11 and C++14. Its item-based lessons on type deduction, smart pointers, move semantics, and lambda expressions are masterclasses in understanding not just how features work, but their pitfalls and optimal applications. For 2022, it should be supplemented with material covering C++17 and C++20. Here, *C++17 – The Complete Guide* by Nicolai Josuttis provides meticulous, practical coverage of that standard’s additions. For C++20, while definitive single-volume texts were still emerging in 2022, Josuttis’s *C++20 – The Complete Guide* was a leading resource, detailing major features like concepts, ranges, and coroutines. These books transition the learner from awareness to practical, effective usage.

However, self-study must also build robust fundamentals in software design and generic programming. For this, *Programming: Principles and Practice Using C++ (Third Edition)* by Stroustrup, while often used in academia, is a viable self-study option for those committed to a long-term, project-based approach that builds from basics to advanced topics. More critically, *The C++ Standard Library: A Tutorial and Reference (3rd Edition)* by Nicolai Josuttis is indispensable. True expertise in C++ is characterized by mastery of its library, and this reference provides both tutorial and exhaustive detail on containers, algorithms, iterators, and utilities. Concurrently, *C++ Templates: The Complete Guide (Second Edition)* by David Vandevoorde, Nicolai Josuttis, and Douglas Gregor, updated for C++17 and C++20, is mandatory for anyone needing to understand and utilize template metaprogramming, variadic templates, and type traits, which are central to professional-grade C++.

Therefore, a structured 2022 self-study path would begin with *A Tour of C++* for orientation, proceed with *Effective Modern C++* and the Josuttis "Complete Guide" volumes for detailed feature mastery, and solidify with the library and template guides. This progression systematically addresses the language's evolution, its paradigm shifts, and its most powerful abstraction mechanisms. Crucially, this curriculum must be paired with active coding against the latest compiler support for C++20 features, as the language's complexity demands practical reinforcement. The goal is not merely learning syntax but internalizing a design philosophy centered on type safety, resource management, and efficient abstraction—the hallmarks of modern C++.
