5.0 out of 5 stars
Excellent for C++ programmers at all levels, August 13, 2004
This review is from: Exceptional C++ Style: 40 New Engineering Puzzles, Programming Problems, and Solutions (Paperback)
This book is not so much about C++ "style" in the usual sense (that is, how to indent or where to put the curly braces) but rather, about sound coding practices that make your code simpler, better, faster, and more maintainable. What you get is a collection of 40 items that each examine a specific topic, outline the potential problems with a particular approach, and then proceed to show you how things can be improved. Most importantly, each item is strong on the rationale: you are not just told how to do it better, but *why* it is is better to do something in a particular way.
There is something for everyone in this book, from the obscure and astonishing ("How many consecutive '+' characters can appear in a standards-conforming program?"), to the pragmatic ("When should you use inlining?"), to the advanced ("How generic should you make your templates, and why?").
I've been programming in C++ for 16 years now, and I learned quite a lot from reading this book. Yet, you don't have to be a C++ veteran to appreciate the advice that is provided: novice C++ programmers will find the items just as useful as old hands at C++ programming.
The book is well written, in clear and concise style, and never boring. (A number of creative footnotes even produce the occasional laugh.) The material is well organized, presented in groups of topics that relate to each other, and the table of contents and index make it easy to locate a topic for reference. And the bibliography contains things that are actually worth reading, rather than meaningless filler material.
I most appreciated Herb's honesty when dealing with various not-so-great aspects of C++. He doesn't shy back from pointing out when things are bad and simply shouldn't be used (such as exception specifications). The items I enjoyed the most are about the design of std::string, which Herb dissects (or should I say "trashes"?) unmercifully. To me, the book is worth buying just for these items alone because they provide splendid insight into what distinguishes good design from bad design, and how methodical and clear thinking is essential to writing good programs. ("Beware the behemoth of the Winnebago class -- it will haunt you onto the fourth generation...")
In summary, I think every C++ programmer should read this book. Yes, it's *that* good.

Simply exceptional, August 5, 2004
This review is from: Exceptional C++ Style: 40 New Engineering Puzzles, Programming Problems, and Solutions (Paperback)
Did you know the "snprinf(...)" that we use in our programs is not part of the C++ standard? Did you know that the "export" keyword has little or no benefit to C++ templates and the source code of the implementation still needs to be shipped? Do you know what primary templates are? Did you know that Accessibility checking is the last things a compiler checks for - after checking for overload resolution? Do you make your virtual functions private? Well, you really should. Do you know what Herb Sutter's favorite Starbucks drink is? Do you know what the "const" keyword really buys you? How about inline-ing?
If you answered no to even one of these questions, you should read Herb Sutter's Exceptional C++ Style, 40 New Engineering Puzzles, Programming Problems, and Solutions book. I must say that I am not doing justice in reviewing this book, since each item in this 40 item collection should really reviewed independently as each one is very well written, useful and practical.
To start, this book is well organized into sections as one would expect such type of organization with book of such type. One differing aspect is with the Case Studies at the end of the book. Mostly around the string class, but nonetheless, they are very informative. The author has taken already-out-there-being-used code and depicts them for their style. Various "guidelines" given by the author in the Case Studies section makes the developer's life a whole lot simpler. One of my favorite guidelines - throughout the book - is the one the author gives about the decision that each developer goes thru when designing a class and wants to make a decision about what to make friend, a member and a non-member of a class:
- Always make it a member if it has to be one.
- Prefer to make it a member if it needs access to internals
- In all other cases, prefer to make it a non-member friend.
Simple? Well, it should be. There are plenty of explanation and example for each of the given guidelines. As one reads and understands the given guidelines, they are very easy memorize-able. Three small phrases which we call have used or even know when we write code, but they are all on paper and are made very simple to be carved in one's memory. The author makes a great deal of effort to follow this routine, an engineering approach to solving problems and designing software, throughout the book. This book is like having an engineering notebook with fun-facts and pointers and hints that you always wanted to know and now you do!
I should really have gone thru the book in some sort of a chronological order, but I figured that the Case Studies are rather unique in this book and require special attention.
Who would have thought that there is so much to the Standard Template Libraries? Did you know that there are functions/methods in the STL that one can not even use with the STL? (Item 4) "...the bottom line is that you can't reliably form pointers to standard library member functions and still have portable code." I was blown away by this bold statement. What do you mean? You want to tell me that standard doesn't really constitute a standard? Want to tell me that my code that I have been so carefully writing using the STL might not be portable after all? There are rather amazing twists in the C++ language, and the author elegantly describes these abnormalities, and it the process the author manages to blow your mind away.
A great amount of attention is given throughout the book to the "boost" libraries. I was not familiar with "boost", and I was interested enough after reading this book that I will make a point to read up on it. The author does make a claim that the boost library might become part of the C++ standard, which would explain why the author has referred to the boost library so much in his text. A good deal of attention was also given to Inheritance and Polymorphism as one would expect. You see this topic all the time in every C++ book, but there are still grounds uncovered and stones unturned. You can't ever have enough of this specific topic. The most intriguing part is Item 16 about a class's Private Parts! If you think that Private members are really hidden, then think again and read Item 16 - you will be amazed at how the C++ compiler treats private members and methods.
Virtuality and virtual classes: you know them as the cause of needing to stay at work late to debug your code, and the reason behind male pattern baldness due to the stress that they cause you. If this is the least bit true, then Item 18 is for you. The best quote out of this item is made when the author talks about public virtual functions: "Prefer to make virtual functions private." Why you ask? Read Item 18 and find out.
A wealth of information is in this book. Herb Sutter has done it again. This book is a must for every C++ programmer as it further unleashes the great power and flexibility of the C++ programming language.

Yet More Exceptional C++, November 11, 2004
This review is from: Exceptional C++ Style: 40 New Engineering Puzzles, Programming Problems, and Solutions (Paperback)
This book is a great addition to Herb Sutter's previous two "Exceptional" C++ books. It follows a very similar question and answer format that helps the reader think about a problem before being given the answer and so is more effective in helping you learn than are some other books. It gives very clear and concise answers to each problem with guidelines drawn from each lesson highlighted throughout the text that help you remember the main points.
The only problem now that I have is, with all three of these books on my shelf, it takes longer to figure out where I read something of on a particular topic. The topical sections of each book overlap (E.g., sections covering exception eafety, memory managment and inheritance appear in all three books.) and they are all written at the same level of difficulty overall. The later books do make plenty of references back to the earlier ones as well as some other very good C++ books but this material would be better organized in one volume rather than three. Perhaps they should have been published as three editions of the same book rather than three separate books. That's the only thing I can think of that would have made them more useful. Even so this book, like the other two, is very good exercise for keeping C++ programming skills sharp. Well done!
