    C++ Tutorial Order Confusion

    The past few weeks I've been following the C++ tutorials at the cprogramming website in order (Clicking the "Next Tutorial: *name*" link at the bottom of each tutorial to go to the next one.)

    After tutorial number 20, there is no "Next Tutorial" button. That slightly confused me, so I went to the tutorial index, found the name of tutorial number 20, and clicked the one after it (Tutorial #20 is Inheritence Syntax in C++, and the one below it in the index is Initialization Lists in C++). I realized quickly that every tutorial after the Inheritence Syntax tutorial number 20 had stuff that flew way over my head, using terminology and syntax that I didn't understand at all. For example, in the Initialization Lists tutorial, part of the example code declares a variable of type "T":

    class my_template
                    // works as long as T has a copy constructor
                    my_template( T bar ) : _bar( bar ) { }
                    T _bar;      << What is that?
    And in the next tutorial, C++ Class Design, the tutorial talks about declaring virtual and non-virtual functions. Neither of those concepts (T variables and virtual functions) mean anything to me.

    Can someone just explain the order that I read each tutorial in, starting right after tutorial #20?


    EDIT: Just in case it isn't completely clear, the reason I don't understand either of those concepts, or several others that have appeared in other tutorials, is because the C++ Tutorials up to that point had not explained those to me yet, which is why I'm wondering if that is the right order to be reading the tutorials in.

    You should read the tutorial on templates in C++ to understand that part. Unfortunately, there appears to be a typographical error, possibly caused by importing the example into HTML. The first line should read:
    template<typename T>
    This also explains what T is: a type name.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Okay thanks, I'll look at that tutorial. That helps me with the "T" variable.

    But is there anyone who can explain the order of the tutorials for me?

    I believe the webmaster is the one who put the list together, perhaps he would be able to answer your question for you.

    Thanks for the heads-up, that is definitely a mistake in the formatting. I've reordered the tutorials a little bit to try and make it better (so that initialization lists comes after templates, for example). Please let me know if you run into any other examples like this.
