Dear all, Consider the following code:

class Person
{
Person *parent;

public:
Person(Person *p){parent = p;}

};

int main()
{
Person grandfather(nullptr);
Person father(&grandfather);
Person son(&father);

// Do something here

return 0;

}

The inter-object relationship works fine, as long as I don't pass the objects around as function arguments (e.g. pass by value) or clone the objects. If I want to pass them as function parameters, or make a clone of the three objects, without breaking their relationships, what should I do? Thanks. Milan.
