Explanation / Answer

Answer:

38) D) Speed: 400; Height: 2000

class Car
{
public:
Car();
Car(double new_speed);
double get_speed() const;
private:
double speed;
};
Car::Car()
{
speed = 0;
}
Car::Car(double new_speed)
{
speed = new_speed;
}
double Car::get_speed() const
{
return speed;
}
class AeroCar : public Car
{
public:
AeroCar();
AeroCar(double new_height, double new_speed);
void display_data() const;
private:
double height;
};
AeroCar::AeroCar()
{
height = 0;
}
AeroCar::AeroCar(double new_height, double new_speed)
: Car(new_speed * 2)
{
height = new_height;
}
void AeroCar::display_data() const
{
cout << "Speed: " << Car::get_speed() << "; Height: " << height << endl;
}
int main()
{
AeroCar acar1(2000, 200);
acar1.display_data();
return 0;
}

Output: Speed: 400; Height: 2000

CashRegister();
CashRegister(int count);
void set_item_count(int count);
void view() const;
