    Nesting classes

    According to my C++ book, the following is legal:
    Code:
    class a_class
    {
              public:
                        int one;
                        int two;
    };
    
    class b_class
    {
             public:
                       int fortytwo;
                       a_class b_a;
    };
    
    b_class b;
    How do I reference the members of an a_class object that is naested inside of a b_class object? Would the following be legal?
    Code:
    b.b_a.one;

    Not the best use of the word nest/nested/nesting. Any programmer would have thought you meant

    Code:
    class A { class B { }; };
    Warning: Have doubt in anything I post.

    GCC 4.5, Boost 1.40, Code::Blocks 8.02, Ubuntu 9.10 010001000110000101100101

    };
    
    b_class b;
    The example you gave would be defined as containment.
    class b contains an instance of class a in other words.
    Nesting would be defining class a in-side of class b as the post above examples.
    My Favorite Programming Line:
    Code:
    #define true ((rand() % 2) ? true : false)

    Ok. Thanks for the help, and for clearing up the terms. I'l be sure to use the term 'containment' to describe this situation from now on.
