Great Book. It helped programmers understand C++ after ANSI standardized the language (ANSI-ISO C++). This book is priceless among developers, the new (at that time) core language was very difficult to understand. ANSI's documentation was like the U.S tax code, and very unwieldy. This book simplified things, I still use ANSI-ISO Standardized C++ to this day because of it. Thanks Mr. Holzner for the timeless contribution.
