    Adding virtual keyword in front of get_price() in Hotel Room is enough.

    class HotelRoom {
public:
    HotelRoom(int bedrooms, int bathrooms) 
    : bedrooms_(bedrooms), bathrooms_(bathrooms) {}
    
    virtual int get_price() {
        return 50*bedrooms_ + 100*bathrooms_;
    }
private:
    int bedrooms_;
    int bathrooms_;
};

class HotelApartment : public HotelRoom {
public:
    HotelApartment(int bedrooms, int bathrooms) 
    : HotelRoom(bedrooms, bathrooms) {}

    virtual int get_price() override{
        return HotelRoom::get_price() + 100;
    }
};

    Nah... I didn't know we were playing find the missing keyword. This took me some minutes while I was thinking why it doesn't work when the calculations are actually correct lol.
