class Pet

{

string pname;

public:

Pet(const string& name) : pname(name) {}

virtual string name() const { return pname; }

virtual string description() const { return "This is " + pname; }

};

class Dog : public Pet

{

string favoriteActivity;

public:

Dog( const string& name, const string& activity): Pet(name), favoriteActivity(activity) {}

string description() const { return Pet::name() + " likes to " + favoriteActivity; }

};

void describe(Pet p)

{ // Slices the object

cout << p.description() << endl;

}

int main()

{

Pet p("Alfred");
