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 use of type-id is a sign that you need virtual functions for myClass. Even if the other two classes are totally independent, the fact that they are returned by the same function could easily make them inherit a base class. And also you can just return a pair containing class1, class2 and one of them can be null.
