Explanation / Answer
Both the objects have a some common properties hence the common properties are written in a superclass and you dont have to define those properties in both the objects seperately.
So the superclass will have the common properties. And the two objects will have their unique properties which is draft in case of boat object and license plate in car object.
Below is the contents of all the classes:
//This is your superclass which will contain common fields
class superclass {
public :
int fuel_capacity;
int serial_no;
int passenger_capacity;
int net_weight;
};
//Car class
class car : public superclass
{
public:
int license_plate;
};
//Boat class
class boat : public superclass
{
public:
int draft;
};
Hope you found it helpful. Thanks.
