i think they looking virtual copy constructor concept how u will implement it.
this is well known problem

For this abstract class will declare a pure virtual clone method and all derived class will inherit it

class Base
{
public:
Base* clone() = 0;
};
class Derived1 : public Base
{
public:
Base* clone()
{
return new Derived1(*this);
}
};

class Derived2 : public Base
{
public:
Base* clone()
{
return new Derived2(*this);
}
};

int main()
{
Base* p = new Derived1();
Base* q = new Derived2();

vector<Base*> v;
v.push_back(p);
v.push_back(q);

//Now suppose u need to clone this vector object

vector<Base*> vc;

for_each(Base* x : v) vc.push_back(x->clone());


}

class Base

       public:
       virtual Base* clone() = 0; //polymorphic nature
