variable return type in c++ class

Question

i have a class with the following structure:

class myClass
{
    private:
        int type;
        classOne objectOne;
        classTwo objectTwo;
    public:
          


        

Answer 1

The first problem is how you will determine the class of which type has been returned. I think it is possible to return a pointer to structure of this type

struct res {
  myClass* c1;
  ClassOne* c2;
} ;

The field of the not chosen class is NULL, the other points to the object.
