Hello, I need help with these 2 C++homework questions. I have provided my code below

#include

#include

using namespace std;

class Vehicle{

private:

string *brand;

public:

Vehicle(){brand=new string;*brand="TBD";}

Vehicle(string b){brand=new string;*brand=b;}

void output(){cout<<"Brand: "<<*brand << " ";}

void setBrand(string b){*brand=b;}

string getBrand(){return *brand;}

};

class Car:public Vehicle{

private:

int *weight;

public:

Car():Vehicle(){weight=new int;*weight=0;}

Car(string b, int w):Vehicle(b){weight=new int; *weight=w;}

void output(){cout<<"Brand: "<

void setWeight(int w){*weight=w;}

int getWeight(){return *weight;}

};

class Boat:public Vehicle{

private:

int *hullLength;

public:

Boat():Vehicle()

{hullLength=new int; *hullLength=0;}

Boat(string b, int h):Vehicle(b)

{hullLength=new int;*hullLength=h;}

void output(){cout<<"Brand: "<

void sethullLength(int h){*hullLength=h;}

int gethullLength(){return *hullLength;}

};

Q3: Continue of previous question (20pt)

1. Copy the previous program to a new file.

2. Convert output function of Vehicle to abstract class.

3. Override output function of Car and Boat class.

Use following main() to test your function (DO NOT CHANGE the int main as any alteration will not be accepted)

int main(){ Vehicle *a;

a = new Car("Honda",2000);

a->output(); // Brand:Honda Weight: 2000

a = new Boat("Baja",100);

a->output(); // Brand:Baja hullLength: 100

}

Output from main: Brand:

Honda Weight: 2000

Brand: Baja hullLength: 100

Q4: Continue of previous question (20pt)

1. Copy the previous program to a new file.

2. Add Destructor and assignment operator to Vehicle class

3. Add Destructor and assignment operator to Car class.

4. Add Destructor and assignment operator to Boat class.

Please indicate call of destructor and assignment operator from all three classes.

Use following main() to test your function.

int main(){

Car a("Honda",2000),b;

a.output(); // Brand: Honda Weight: 2000

b.output(); // Brand: TBD Weight: 0

b = a;

b.output(); // Brand: Honda Weight: 2000

b.setBrand("Tesla");

b.setWeight(3000);

b.output(); // Brand: Tesla Weight: 3000 a.output(); // Brand: Honda Weight: 2000 Boat c("Baja",100),d;

c.output(); // Brand: Baja hullLength: 100

d.output(); // Brand: TBD hullLength: 0

d = c;

d.output(); // Brand: Baja hullLength: 100

d.setBrand("Bertram");

d.sethullLength(60);

d.output(); // Brand: Bertram hullLength: 60

c.output(); // Brand: Baja hullLength: 100 }

Output from main:

Brand: Honda Weight: 2000

Brand: TBD Weight: 0

==> Car Assignment operator.

==> Vehicle Assignment operator.

Brand: Honda Weight: 2000

Brand: Tesla Weight: 3000

Brand: Honda Weight: 2000

Brand: Baja hullLength: 100

Brand: TBD hullLength: 0

==> Boat Assignment operator.

==> Vehicle Assignment operator.

Brand: Baja hullLength: 100

Brand: Bertram hullLength: 60

Brand: Baja hullLength: 100

==> Boats Destructor.

==> Vehicle Destructor.
