Written for the intermediate or advanced C++ programmer, renowned C++ expert Scott Meyers provides essential techniques for getting more out of the Standard Template Library in Effective STL, a tutorial for doing more with this powerful library.
STL is a hugely powerful feature of today's C++, but one with a well-earned reputation for complexity. The book is organized into 50 tips that explore different areas of the STL. Besides providing a list of dos and don'ts, Meyers presents a lot of background on what works and what doesn't with STL. Each tip is demonstrated with in-depth coding samples, many of which make use of two-color printing to highlight the most important lines of code. (Advanced developers will enjoy Meyers's in-depth explanations, while those who are in a hurry can skip ahead to the recommended tip itself.)
A good part of this book involves using containers, like vectors and maps, which are built into STL. (Besides the standard built-in containers, the author also highlights recent additions to STL like B-trees, which are available as extensions from other vendors.) You'll learn the best ways to allocate, add, change, and delete items inside containers, including associative containers like maps. You'll also learn to avoid common pitfalls, which can result in writing code that is slow or just plain wrong.
Other areas covered in Effective STL cover getting the most out of the 100-plus STL algorithms that are bundled with this library. Meyers shows you how to choose the correct algorithm for sorting and other functions. (Even advanced developers will learn something here.) Sections on using function objects (called functors) round out the text. Meyers shows you when these classes make sense and the best ways to implement them. Besides specific tips, you'll get plenty of general programming advice. A useful appendix shows the limitations of STL as implemented in Microsoft Visual C++ 6.0 and how to overcome them.
Overall, Effective STL is a really invaluable source of programming expertise on an essential aspect of today's C++ for anyone who is using--or planning to use--STL in real production code. It is quite simply a must-have. --Richard Dragan

From the Back Cover
"This is "Effective C++" volume three - it's really that good."
- Herb Sutter, independent consultant and secretary of the ISO/ANSI C++ standards committee "There are very few books which all C++ programmers "must" have. Add "Effective STL" to that list."
- Thomas Becker, Senior Software Engineer, Zephyr Associates, Inc., and columnist, "C/C++ Users Journal" C++'s Standard Template Library is revolutionary, but learning to use it well has always been a challenge. Until now. In this book, best-selling author Scott Meyers ("Effective C++," and "More Effective C++") reveals the critical rules of thumb employed by the experts - the things they almost always do or almost always avoid doing - to get the most out of the library. Other books describe "what's in" the STL. "Effective STL" shows you "how to use it." Each of the book's 50 guidelines is backed by Meyers' legendary analysis and incisive examples, so you'll learn not only what to do, but also "when" to do it - and "why." Highlights of "Effective STL" include:
- Advice on choosing among standard STL containers (like vector and list), nonstandard STL containers (like hash_set and hash_map), and non-STL containers (like bitset).
- Techniques to maximize the efficiency of the STL and the programs that use it.
- Insights into the behavior of iterators, function objects, and allocators, including things you should "not" do.
- Guidance for the proper use of algorithms and member functions whose names are the same (e.g., find), but whose actions differ in subtle (but important) ways.
- Discussions of potential portability problems, including straightforward ways to avoid them.

I was one of the reviewers and in the beginning I thought that reviewing a book on STL is going to be an easy enough task. I was wrong.
I learned lots of new things on using STL effectively: why `empty()` is better than `size() == 0`, when and how to write custom allocators, how std::string might be implemented, how associative containers distinguish between equality and equivalence, how to implement associative containers as sorted vectors (that's a gem!), and many, many other things that I either had a blurry understanding of, or simply didn't know about. Now I'm glad I do, because my understanding of the STL and the practical use of it are much better.
The book went through an extensive review process; it is really combed and distilled to its finest. I recommend it to any C++ programmer who uses STL - which should be, any C++ programmer, period. Five well deserved stars.
Before I started this book, I thought STL was kind of neat. It had some useful containers. It was nice to be able to use a list or map or string class that had already been tested.
Boy, was I underestimating the power of STL. This book has made me a big STL fan, but I'm not reviewing the STL now so I'll leave that topic alone... Thanks to Scott Meyers, I have a much better grasp of the capabilities and limitations of STL. I can use it to do a lot more. I write more concise code that's easier to read and debug. I make better choices about which containers to use. I recognize situations where I can use an STL algorithm instead of many lines of my own code.
In short, I look at the STL code I wrote before and laugh... I mean, it all works, but the Meyers book has taken my use of (and appreciation for) the STL to a whole new level. I recommend this book for any C++ developer who isn't already an STL expert.
An update, 2 years after the above text was written: I still recommend this book to people and still think it's the best STL book I've read.
The presentation is very much up-to-date (even to the point where it anticipates some of the forthcoming updates to the C++ standard). The writing style is clear and precise without sounding academic or condescending, and the book has an index that actually works.
"Effective STL" is every bit as good as "Effective C++" and "More Effective C++". No C++ programmer should still be writing code without the STL, and no-one writing code with the STL should be without this book. Buy it!
Come on Scott, write a second edition!
All of this is good to know, but I didn't find it as useful as his other two Effective books. Other than the use of the built in looping functions like for_each the book didn't really provide me with many new "tricks" for my "bag."
However, all the information in the book is useful, and the intermediate level STL programmer will probably learn a lot of ways to avoid problems by reading this book. Hopefully there will be a second edition in the future that will give the book a little more utility.
I user several STL books regularly and none of them have come close to giving me the in depth understanding that this book has. Sure, others are better references, beginner guides, etc.. but if you really want to understand what is going on under the covers and how to write -good- STL, this book is your answer. I have seen suggestions from this book result in massive performance improvements in naively written STL code.
Enough said, go pick up a copy .. :)
