Tour of C++, A (C++ In-Depth Series)

From the Preface

"C++ feels like a a new language. That is, I can express my ideas more clearly, more simply, and more directly today than I could in C++98 or C++11. Furthermore, the resulting programs are better checked by the compiler and run faster.

Like other modern languages, C++ is large and there are a large number of libraries needed for effective use. This thin book aims to give an experienced programmer an idea of what constitutes modern C++. It covers most major language features and the major standard-library components.

...the aim here is not mastery, but to give an overview, to give key examples, and to help a programmer get started [with C++ 20]."

— Bjarne Stroustrup, designer and original implementer of the C++ language
