(d)

Object

Which of the following is true with respect to inheritance?

(a)

Private members of base class are inherited to the derived class with private.

(b)

Private members of base class are not inherited to the derived class with private accessibility

(c)

public members of base class are inherited but not visible to the derived class.

(d)

Protected members of base class are inherited but not visible to the outside class.

class vehicle
{ int wheels;
public:
void input_data(float,float);
void output_data();
protected:
int passenger;
};
class heavy_vehicle : protected vehicle {
int diesel_petrol;
protected:
int load;
public:
void read_data(float,float)
void write_data(); };
class bus: private heavy_vehicle {
char Ticket[20];
public:
void fetch_data(char);
void display_data(); };
Which is the base class of the class heavy_vehicle?

(a)

Bus

(b)

heavy_vehicle

(c)

Vehicle

(d)

Both (a) and (c)

class vehicle
{ int wheels;
public:
void input_data(float,float);
void output_data();
protected:
int passenger;
};
class heavy_vehicle : protected vehicle {
int diesel_petrol;
protected:
int load;
public:
void read_data(float,float)
void write_data(); };
class bus: private heavy_vehicle {
char Ticket[20];
public:
void fetch_data(char);
void display_data(); };
The member function that can be accessed by an objects of bus Class is

(a)

input data(), output _data()

(b)

read _data() ,write _data()

(c)

fetch _data(), display_data()

(d)

All of these
