Engaging with C++11 and C++14 is more than just familiarizing yourself with new features like automatic type declarations, move semantics, lambda expressions, and concurrency support. The challenge lies in effectively utilizing these features to ensure your software is correct, efficient, maintainable, and portable. This practical book comes into play here. It describes how to write truly great software with C++11 and C++14, that is, with modern C++. Topics include the advantages and disadvantages of brace initialization, noexcept specifications, perfect forwarding, and functions for creating smart pointers; the relationships between std::move, std::forward, rvalue references, and universal references; techniques for writing clear, correct, and effective lambda expressions; how std::atomic differs from volatile, how each should be used, and how they relate to C++'s concurrency API; as well as best practices.
