    Honestly, I have not seen any documentation or tutorial
    available online (available free) that is as useful as the
    documentation of the C language and of the rest of the C++
    language.
    Normally I agree with what Sam posts, but in this case I
    disagree that most programmers can effectively learn
    "the rest of the C++ language" from on-line (available free)
    documentation. Certainly not from MSDN (in my opinion).
    MSDN gives the syntax, but has very little info on C++ design.
    (I admit, that the flaw might be with me, and not MSDN - I'm
    certainly not a programming expert and using MSDN to learn
    C++ might just be beyond my capabilities. Maybe real computer
    programmers can.)

    Look at the following code posted by a "stl-basher" in the
    Visual C++ forum. He claimed that it was a great design.
    However, the design is flawed - and flawed in a very basic way.
    But I doubt that looking at MSDN will show why. (I spent about
    30 minutes searching MSDN and could not find anything ...
    maybe its there and I missed it.) And public inheritance is
    basic to the C++ language.


    Code:
    class CUpperCaseString : public CString
    {
    public:
        CUpperCaseString(LPCSTR szString)
            : CString(szString)
        {
            MakeUpper();
        }
    
        virtual ~CUpperCaseString()
        {
        }
    };
    What is the difference between public and private inheritance,
    and when/why would you ever use private inheritance? I
    searched for that in MSDN and came up empty. Again, maybe its
    there somewhere.

    Pretty much look at any of the points in Meyers Effective C++
    books. I have not found on-line documentation that covers the
    majority of them in proper detail.

    Personally, I don't even think the documenation for the MFC
    classes is any good. I have never found any complexity
    guarentees on performance for the various functions. About all I
    can find is that "inserting into a CArray is slow" and
    "inserting into a CMap is fast". I agree with both those
    statements in GENERAL, but I can also show examples where
    the statements are not true. And while performance is not an
    issue in all programs, it is certainly an issue and many codes.


    Some on-line sites that I find useful (both STL and C++ in general)

    http://www.josuttis.com/libbook/idx.html
    http://www.gotw.ca/gotw/
    http://www.aristeia.com/publications_frames.html

    and not leave out MSDN ...

    I think I pretty much agree with you, Philip. Please understand that you are coming from the opposite direction. I did not say that the MFC documentation and the rest of the MSDN is wonderful. I was just saying that they are better compared to ths STL documentation.

    What is critical here is the definition of "effectively learn". What I am saying is that it is generally possible to learn enough to write a program using C and C++. That might not be true, but if not then that would support the important point of what I am trying to say; that is, that the STL documentation is not sufficient for using the STL. Good software design is a different matter, and the STL documentation is worse in that manner, not better.

    Fair enough, you must have an introduction other than just reading the SGI docs. This is done in varying degrees on some sites and in articles available online (e.g. std::vector by Gabriel). My point is that once you understand the concept of STL (iterators, containers, algorithms, templates), you don't need a book anymore. There are advanced techniques that are only in books, but for most of the how do I use this-type questions, the SGI docs are sufficient. But yes, it's not for the uniniatiated. I.e. if you want to learn the concepts of STL, it's a bad idea to start only from the docs. But if you have used vector, string and map, you just need the SGI docs to see what a deque and a multiset do and how to use them.

    Get this small utility to do basic syntax highlighting in vBulletin forums (like Codeguru) easily.
    Supports C++ and VB out of the box, but can be configured for other languages.

    I have been quite frustrated trying to use the documentation for determining some very basic uses of STL.

    Maybe. I've always found what I was looking for, except for the stuff about allocators and advanced techniques, like how to best combine several things into others.
