Practical C++ Programming, Second Edition 266

Posted by timothy from the pretty-good dept.
adrienlamothe writes "Practical C++ Programming is dedicated to teaching the reader how to program in the C++ programming language. The book actually has four goals: 1) Teach the reader C++. 2) Instill good programming style and practice (indeed, the book's subtitle is 'Programming Style Guidelines.') 3) Teach the programmer basic software development concepts. 4) Introduce the reader to debuggers and the make utility. 4) The author encourages the reader to use a computer to enter, run and debug the book's programming examples. I concur with this advice, though it isn't absolutely necessary." To see how well the book meets its own goals, read on for the rest of Lamothe's review.
Practical C++ Programming, Second Edition
author Steve Oulline
pages 549
publisher O'Reilly & Associates
rating 7
reviewer Adrien Lamothe
ISBN 0596004192
summary Guide to learning C++ and programming style.

Practical C++ Programming is a fairly large book: 549 pages organized into six parts containing 30 chapters and 5 appendixes. The parts are as follows:

  1. The Basics
  2. Simple Programming
  3. Advanced Types and Classes
  4. Advanced Programming Concepts
  5. Other Language Features
  6. Appendixes.
You will have to read most of the book in order to learn C++, although there are a number of chapters you can avoid if your goal is to learn only the language's mechanics.

I must start by saying that I like the book -- I think it has value. There are a number of things I really appreciate about the book. There are also some problems that adversely impact one segment of the book's intended audience (more about those later.)

The book discusses all the essential elements of C++. Areas covered include: Class definition, namespaces, scope definition and resolution, operator and function overloading, object memory allocation (i.e. new and delete,) type casting, exceptions, inheritance, templates (including an introduction to the Standard Template Library,) the Input/Output system (including the C I/O library), and pointers. All language operators are discussed (i.e. relational, assignment, etc.) Also covered are language elements that C++ has in common with C. The other areas of instruction (programming style, software development concepts, programming tools) are intertwined with the primary topic throughout the course of the book.

One of the book's strong points is the author's excellent conversational writing style. It's hard to find books that combine good technical information with clear expository writing (O'Reilly seems to publish most of them.) Practical C++ Programming definitely succeeds in this area. The author frequently references his own experience to reinforce concepts on programming style, design and debugging. I found his anecdotes useful and occasionally humorous. The book also contains small sections of text that serve to warn the reader of pitfalls (these are marked with a bear trap icon) and areas where caution should be exercised (marked with bear paw tracks). Also, some of the source code examples contain intentional bugs, which the author explains at the end of each chapter. Diagrams, tables and source code examples are found on almost every page of the book, and these are used to keep the reader engaged with the textual discourse. My favorite diagram is Figure 7-1. "Software life cycle," on page 88; I emphasize with the dinosaur.

The book contains some interesting programming examples. The chapters on operator overloading and floating-point math contain source code illustrating how to deal with the numeric precision problems that plague all computers and computer languages. The chapter on the Standard Template Library contains a program showing how to create and use objects that manage a simple roster for enrollment and grading of students. The book also contains several examples of linked-lists and trees, for the purpose of teaching the reader how to use pointers, and to also show the reader the power and usefulness of the Standard Template Library.

Now to speak about the book's shortcomings. First, although the book does a good job of covering the important C++ topics of classes, inheritance, and templates, I think it falls a bit short in these areas (especially the coverage of inheritance). Also, the terms instantiation, polymorphism and encapsulation are not used in the book. The book could have provided a bit more insight into object-oriented concepts. Also, these areas of the book are sparsely diagrammed. Second, source code errors and typos appear regularly enough to frustrate an inexperienced reader. I also found a couple of diagrams to be confusing. Third, there are occasional misleading statements that a beginner probably won't recognize as such. Because of these problems, I cannot recommend the book to people with no previous programming experience. I'm surprised that these problems made it into a second edition.

I think that despite these problems, the book has value to experienced programmers who want to learn C++. C programmers in particular will have an easier time dealing with the source code errors. Also, I think that the book can be used by beginning programmers in a classroom environment, providing the instructor understands the book's problems and is prepared to guide students around them. The book should be particularly useful when read in conjunction with a good C++ reference guide.

Practical C++ Programming is an ambitious work in its breadth and depth. It covers more areas of software development than other C++ books. It takes an interesting approach that some readers will appreciate and others may not.

I would like to have seen a more detailed and complete explanation of the object-oriented aspects of C++ (including more diagrams). A table showing all functions for Standard Template Library containers would have been nice (the book does make reference to two STL web sites). Some mention of third-party object libraries (such as Rogue Wave, Qt, etc.) and their uses would have been helpful.

The lack of a detailed explanation of inheritance may not be bad. I'm one of those who believe that heavy reliance on inheritance causes serious maintainability problems. However, I think the book should have covered this topic more fully, so the reader would understand this issue.

In summary, Practical C++ Programming is a good book that really shines in some aspects and falls short in others. With some improvement, it could be a great book.

      Actually it doesn't always work. On more than one occassion I've seen a bug stop happening when I put in a print statement. Take the print statement out, bug comes back.

      This always indicates some kind of memory error, usually an overflow of a local buffer, or a bug in your pointer arithmetic somewhere. By making the call to printf() you are modifying the contents of the stack (by pushing the function arguments) and this changes conditions in such a way that the bug no longer occurs.

      It's called a "Heisenbug" :-)

      • Even worse is when you do something like use the same function two times in a printf() line. Sometimes, for some reason, it will print the same results for both functions even if the two have different arguments.

        Someone told me it was due to the memory addresses and caching or something. I haven't been able to duplicate it except by accident. :)

        It's not always a memory error. On fast, multi-threaded apps, it is sometimes timing related. That little bit of time it takes to dump some text out to console is often just enough to mask any synchronization problems.
        • The standard way to debug anything is to trace execution and to reveal the program state at points along that trace. A debugger with watches, breakpoints, and variable evaluation is perhaps a runtime counterpart to the edit-compile-execute cycles of printf() statements, so apart from the quickness of the debugger, I don't see what is so different with printf(). The debugger is so supposed to be more inobtrusive (printf() masking a bug by shifting stuff around in time or in memory space), but I am hardpres

          • Visual C++ (and I believe Borland's C++ Builder post v4) support debugging across libraries and processes. Just start your EXE and make sure all the DLLs have debug information, and you can happily put breakpoints into them, step into them, etc. Also works for out-of-process components, although the best there is to run the component in a separate IDE/debugger session.

            Uh, use Visual C++? All my apps are split into DLLs. When I'm stepping through something in the debugger, I neither notice nor generally care that I've crossed a DLL boundary. (Except when I'm tracking a memory leak, in which case I notice on purpose...) Most of the time I'm setting a breakpoint deep in the guts of some dll and letting the rest just run until it gets there.

        In other words, adding printf()'s and observing the resulting behaviour change allowed you narrow down what was going on and eventually fix the bug. Or to put it another way, the printf() debugging worked. So your "doesn't always work" claim isn't supported by this example.

        • But it didn't work the way you expected it to :-) And sometimes (e.g., late at night, early in morning) that makes it harder to infer the real cause.

          On Linux I've had a ton of success using Valgrind [kde.org] to find memory errors. It can identify bad memory reads, writes, uninitialized values, etc. during runtime. Figuring out what is causing those errors is up to you, however. It doesn't substitute for intelligence but it helps narrow the search incredibly.

      Of course it always works. But since you put print statements everywhere your program probably doesn't do much besides print out the same thing every time you run it ;)

      Actually now that I think about it, your program doesn't even compile. You cannot call a print function without first declaring or defining it, but since you used print statements everywhere you obviously haven't defined it.

    ...should, I have decided, always involve the text Accelerated C++, by Koenig and Moo. They have been working with C++ since its inception, down the hall from Stroustrup.

    The book takes two relatively new approaches to teaching C++: 1) don't teach C first, and 2) assume that the standard C++ library is there. So, they introduce "Hello, World" using std::string and std::cout, and they keep using std::string without trying to first teach template classes with default template parameters. The resulting intro programs are very clean and simple, easy to follow.

    The word "pointer" isn't even mentioned until chapter 9. By that point, they're using strings and vectors to solve useful programs, and since both of those containers manage memory themselves, the user needs to know nothing about dynamic memory management (and thus, pointers) before doing the exercises.

    Pointers and user-defined types are introduced, of course, but they don't need to be introduced before showing the reader how to use the basic library features. You don't need to know how an internal combustion engine works before learning how to drive, although going back later and learning what's under the hood will always reward the observant driver.

    This approach has gotten rave reviews, and from actual C++ people, not just fluff reviewers. It's the produce of years of teaching C++ courses.

    Final note: the book is one of the fantastic "C++ In-Depth" series, of which Stroustrup is the series editor. All are very high quality. One of the series' rules is that the main body of the book can be no more than 300 pages, so "make your point, make it simple, make it clear" rules the day.

There are a lot of areas that merit greater attention and that will get beginners started on the right foot - and messing with raw pointers isn't one of them.

    On top of trying to get the basic OO mindset accross (yes instantiation, polymorphism and encapsulation are big words but the concepts are essential and not that difficult to explain), I'd like to see some more modern and useful concepts explored in depth. For instance:

    • Everything you can find that has to do with automated memory management (smart pointers and such)
    • The STL. The STL. I know it's a rite of passage, but I'm tired of seeing every newbie struggling with his own linked list implementation
    • Reuse. The Boost [boost.org] library can teach you a lot about this and demonstrate that focusing on your problem is more fun than writing boring code that's been done a million times before
    • Design patterns. At least an introduction, dammit.
    • Generic programming, in general ;)

    Just my $0.02 for potential authors out there.

    • There are a bunch of books that address these areas. Some quick ones off the top of my head:

      Modern C++ Design
      Exceptional C++
      The Standard Template Library
      IOStreams and Locales
      Effective C++

      I could go on. Sadly though, not nearly as many C++ programmers read this kind of stuff as should.

      The rest of the card doesn't look much better. The reserved words are listed and the card notes that they can't be used as identifiers, but it doesn't mention that there are other reserved identifiers.

      The description of while(x) says that x must be an expression, but for a long long time C++ has allowed a variable declaration at this point, and such use is idiomatic.

    Back when O'Reilly had a _Practical_C_ book, but no _Practical_C++_ book, I called them and said that they should do one. They rejected my suggestion without pause, saying that their kind of readers didn't think that C++ was better than a pitcher of warm spit. Then some other author came out with a _Practical_C++_ book (now out of print), which wasn't very practical, since it was muchly about the C++ standard, which wasn't a standard then and had barely started to congeal when the book was written. Hence, when O'Reilly finally realized that their old readers had already been educated far beyond their intelligence and that they needed to broaden their appeal, they came out with _Practical_C++_Programming_. You can't copyright a title, but at least it cuts down on the confusion. Now it's gone multiple editions. It's pretty good, but nothing is worse than being ahead of your time before the world is ready.

    >The author encourages the reader to use a computer to enter, run and debug the book's programming examples. I concur with this advice, though it isn't absolutely necessary.

    This is something that novice programmers are well advised to listen to. I constantly am asked by junior programmers 'What happens when I do x', where x is something simple, like try to print out an array.

    Half the time, the problem can be answered by simply trying it. And the other half of the time, you end up with a better question (I want to print out the values of an array, but print @array didn't work. What's the trick?) (In perl, see 'perldoc -f join'. That's not my point, but I don't want to leave you hanging!)

    And even better, learning the value of experimentation makes you a better programmer, and a much more pleasant junior employee. Instead of spending all your time asking a series of questions, you try a whole bunch of things. By actually stopping to think about the problem, which this approach forces you to do, you end up learning a lot more, and sometimes the failed efforts are exactly what you need later. And if you're stumped, you still end up looking smarter, because you at least tried some approaches. And more often than not, it's easier to learn the answer if you've taken the time to struggle with and really learn the problem you're trying to solve, and remember the answer next time.

    I think this is one of the unheralded keys to becoming a good professional programmer.

    Caveat: This works a lot better in some development environments than others. I do most of my work in perl, which is ideally suited to this rapid prototype approach. In environments with long compile times, it's more tedious. This is thankfully decreasingly true, with faster machines making the hours-long compiles a historical problem, so take advantage of it, learn to experiment, and reap the rewards.

      Unfortunately, C++ is complex, and undefined behavior will upset most attempts at experimentation. For example, suppose a beginning C++ programmer wants to change a string's contents so it contains the text "Count is $count" (Perl-ish code). Most of the time they try stuff like:

      int count = ...;
      string s = ...;
      sprintf( &s[0], "Count is %d", count );
      sprintf( (char*)s.c_str(), "Count is %d", count );

      Does that work? Well, maybe, but the code's not guaranteed to work, and it's dangerous. But the problems with the code will not be recognized by the beginner, and therefore experimentation can lead him to assume something is correct even when it is not. The generally accepted answer of

      ostringstream oss;
      oss << "Count is " << count;
      string s = oss.str();

      is not likely to be discovered through experimentation.

      In general, I agree that experimentation is good. C++ just isn't a safe environment and makes trial-and-error programming difficult.

    Instead of comparing just B&N vs. Amazon all of the time, why not use the book shopping bots? (Amazon and B&N are not the cheapest books every time you buy a book (they may be in this case (I checked), but in many cases, the others are much cheaper)! The bots search a lot of the book stores and rank the prices (including handling/shipping), present opportunities for discounts, and even point out the ability for finding books which may be out of print but can be purchased used.

        Just the fact that the prefix operators don't require a temp variable; so if you just need the side effect, use prefix.
