Thread: Dynamic data members?

Thanks for your advice, but I don't think that understanding inheritance is my problem, since I'm rather new to C++ but not object-oriented programming.

The abstract class was only an idea for solving this "dynamic data structure" issue.

The "base" class should provide a get and a set interface method which are supposed to be overridden by descendant classes for setting and retrieving different data types.

Given the following case:

Code:

class Base
{
};

class A : public Base
{
 public:
  int get() { return _value; }
  void set ( int value ) { _value = value; }

 private:
  int _value;
};

class B : public Base
{
 public:
  string get() { return _value; }
  void set ( string value ) { _value = value; }

 private:
  string _value;
};

typedef CArray<Base> MyTableRow

class MyTable
{
....
 protected:
 CArray<MyTableRow> _myTableRows
};

I would like to know how to access A's or B's get and set methods from _myTableRows.

Since I do not think, that this attempt leads to the right direction, I ask you, whether there is a different way to solve my problem of a dynamic data structure without creating lots of different methods which do actually the same on different data types.
I hope I could clearly explain myself this time...
