In the first edition of Thinking in C++, Bruce Eckel synthesized years of C++ teaching and programming experience into a beautifully structured course in making the most of the language. It became an instant classic, winning the 1995 Software Development Jolt Cola Award for best book of the year. Now, Eckel has thoroughly rewritten Thinking in C++ to reflect the final ANSI/ISO C++ standard. Every page has been revisited and rethought, with many new examples and exercises -- all designed to help you understand C++ "down to the bare metal," so you can solve virtually any problem. Eckel starts with a detailed look at objects, showing how C++ programs can be constructed from off-the-shelf object libraries. This edition includes a new, chapter-length overview of the C features that are used in C++ -- plus a new CD-ROM containing an outstanding C seminar that covers all the foundations developers need before they can truly take advantage of C++. Eckel then walks through initialization and cleanup; function overloading and default arguments; constants; inline functions; name control; references and the copy constructor; operator overloading; and more. There are chapters on dynamic object creation; inheritance and composition; polymorphism and virtual functions, and templates. (Bonus coverage of string, templates, and the Standard Template Library, can be found at Eckel's web site.) Every chapter contains many modular, to-the-point examples, plus exercises based on Eckel's extensive experience teaching C++ seminars. Put simply, Eckel has made an outstanding book on C++ even better.
