Instance tracing problem....Please help

i have B class which is inheriting from A and XYZ...
like this...

Code:

                           A        XYZ
                           ^         ^
                           |         |
                         ---------------
                                |
                                |
                             B

A has a datamamber 
class
{

          protected:
             C options;
          public:
	     C optionsPublic;
};
B has a function start();


 

C has a vector oftype vector<D*> and D is the inner class

of the C...Like this

Code:

class C
{
   class D 
       {
       };
       typedef vector<D*> optionlist;
       protected:
       oprionlist optionlistvector;
};

C has some functions AddOptions()
where it is updating the "vector optionlistvector"...
my question is....
How to use the optionlistvector???....its values???....using the following information....
If you want any please let me know....I think i need to learn about instances....
