Question

write a c++ program

A class called car (as shown in the class diagram) contains: o Four private variables: carId (int), carType (String), carSpeed (int) and numOfCars (int). numOfCars is a static counter that should be  Incremented whenever a new Car object is created.  Decremented whenever a Car object is destructed. o Two constructors (parametrized and copy constructor) and one destructor. o Getters and setters for the Car type, ID, and speed. And static getter function for numOfCars. o All member functions that do not modify data members should be constant. o A function print() that prints the details of object.

Write the main function that uses car class as follows:  Print out the number of available cars.  Declare 3 objects of type car. Ask the user to enter the details of these objects.  Print out the details of the three objects.  Print out the Car ID of which is speeder.  Print out the number of available cars.  Add a new function called newCarthat receive the second object as parameter. User the Psuecode below to write the function body: void newCar( ob: car){ Declare new object of type car as a copy of ob. Print the number of available cars. }  Call the function in the main.  Print out the number of available cars.

Answer 1

class car

{

private:

int carId;

string carType;

int carSpeed;

static int numOfCars;

public:

car(int Id, string Type, int Speed)

{

cin>>Id;

cin>>Type;

cin>>Speed;

carId=Id;

carType=Type;

carSpeed=Speed;

numofCars++;

}

car( car &c2)

{

carId=c2.cardId;

carType=c2.carType;

carSpeed=c2.carSpeed;

}

~car()

{

numofCars--;

}

void print(int carId,string carType, int carSpeed)

{

cout<<carId;

cout<<carType;

cout<<carSpeed;

}

void newCar(car c)

car c4=c;

cout<<numofCars;

};

int main()

{

car c1,c2,c3;

c1.print();

c2.print();

c3.print();

cout<<"the no of available cars are"<<numofCars;

newCar(c2);

}
