Effective C++ 3/e is a complete update of Effective C++ and Effective C++ 2/e .
Like its predecessors, 3/e has 55 guidelines which contain better, more
effective ways to write code, backed by specific examples. The second edition
published in 1997, and was basically a face-lift of the first edition, keeping most
of the same elements, and seven years later is still selling well.
Now, Meyers has dramatically rejuvenated the material, including more than
30% brand-new material. Meyers began this edition by asking himself, "What
are the 55 most important pieces of advice for practicing C++ programmers in
2005?" He also asked thousands of past users of his books this same question.
This resulted in a completely new book. New material includes use of UML
notation, thread safety, exception safety, design patterns, and templates. Any
older material has been revitalized to reflect new ideas and strides in C++
