Effective C++: 55 Specific Ways to Improve Your Programs and Designs (3rd Edition) (英语) 平装 – 2005年5月22日
Scott Meyers is one of the world's foremost authorities on C++, providing training and consulting services to clients worldwide. He is the author of the best-selling Effective C++ series of books (Effective C++, More Effective C++, and Effective STL) and of the innovative Effective C++ CD. He is consulting editor for Addison Wesley's Effective Software Development Series and is a founding member of the Advisory Board for The C++ Source (http://www.artima.com/cppsource). He holds a Ph.D. in Computer Science from Brown University. His web site is http://www.aristeia.com.

Each of the 55 "Tips" are quite short and fairly self-contained, and the Author's friendly style makes this book an extremely easy read to boot. If you don't know why you'd bother to use a "const", why you'd use the more complicated C++ casts when the C-style casts work just fine, or why you would ever declare a constructor to be private, then it's time to pick up this book. Even if you do know all of these things, this book will almost certainly teach you something, or at least remind you of a few techniques. This should be everyone's second book on C/C++. Highly recommended.
This book is not a "how to program" in C++.
What the author has done is outline some very important aspects of C++ programming that are either not taught in the typical college curriculum, or easily forgotten, or completely misunderstood.
This book has 55 topics. The order they are listed in kinda makes sense. Overall it seems that the topics are listed from simple first to complicated last. There is a short introductory chapter explaining the order of the topics.
I really like how the author describes C++ as a "federation" of languages. That's in the first chapter/introduction. It just keeps getting better and better.
A few of the topics were common sense and made me wonder if it was really worth mentioning. However, I see some really stupid idiotic code on a daily basis, so apparently there are programmers out there that need to be reminded of the basics.
Some of these topics blow my mind. I mean really, this guy must have spent months just researching the behaviors of the C++ compiler to figure some of this stuff out.
I have nothing negative to say about this book.
Highly recommend this book to anyone seriously into C++, along with "Effective STL", and perhaps also "More Effective C++" (I'm a little less enthusiastic about the last one, but still worth having in your library). Probably also some other title for the transition to C++11 will be required, but I'm not sure yet what to recommend for that.
The book discussed 50 more ways in different items for effective C++ programming. In each item, besides to show a proofed convention or idiom of doing something, it often provides another way to achieve the same goal, which is more intuitive but plausible. Had I been more "diligent" in exploring my own way of developing the software, I would have probably stepped onto those pitfalls for dozens of times, some of which are even very subtle and hard to detect.
This book assumes that you already used C++ and understand its fundamentals. Scott's goal is not to teach the fundamentals but to advice readers on how to use the language effectively - generating good, efficient, re-usable, portable code. On this goal, he was successful. Its pretty much like when I was learning Japanese. I understood the fundamentals and word translations but in order to effectively communicate in that language, I had to be familiar with proper sentence construction, various formalities (some words are not appropriate for certain settings or people) and word dynamics as well. In a sense, this book (or Scott) is your sensei to good C++ programming.
