C ++ Terminology - Participants

By "class members" can be understood all of this:

• data members
• member functions
• nested types

So, if you have this class:

class A
{
    typedef std::string value_type;  //nested type
    value_type  v;                   //data member
    int         w;                   //data member
    void f();                        //member function
    struct B {};                     //nested type
};

the value_type, v, w, fand Bare members of the class A.
