For example:

abstract classes as interfaces class hierarchies for object-oriented programming templates as the basis for type-safe generic software exceptions for regular error handling namespaces for modularity in large-scale software run-time type identification for loosely coupled systems the C subset of C++ for C compatibility and system-level work standard containers and algorithms standard strings, I/O streams, and numerics C compatibility, internationalization, and exception safety

Bjarne Stroustrup makes C++ even more accessible to those new to the language, while adding advanced information and techniques that even expert C++ programmers will find invaluable.

Past readers will find that the new edition has changed a great deal and grown considerably to encompass new language features, particularly run-time type identification, namespaces, and the standard library. At the same time, readers will recognize the lucid style and sensible advice that made previous editions so readable and enjoyable. Probably the biggest change is a substantial new section, well over 200 pages in length, covering the contents and design of the C++ standard library, the most important new feature of the C++ specification. The author has also added a substantial number of new exercises while keeping many from previous editions that have retained their value.

While The C++ Programming Language is not a C++ tutorial, strictly speaking, anyone learning the language, especially those coming from C, will greatly benefit from the clear presentation of all its elements. It is impossible to overstate the importance of this book for anyone who is serious about using C++.
