Two objects of the same class, say "mylnstance1" and "mylnstance2",are declared in a program as a collection of some type (say an ArrayList). mylnstance1 is initialized but mylnstance2 is not.Then mylnstance1 is copied to mylnstance2. If the copy is performed asa copy constructorcopy, two collections exist after the copy but the two collections share all the same elements.

Write C++ code for a class named MuniBus that has the following private member variables: int totalPassengers; double faresCollected; and the following public member functions: void passengerBoard() - adds 2.50 to faresCollected and adds 1 to totalPassengers double getFaresCollected() - returns faresCollected int getPassengers() - returns totalPassengers void reset() - sets totalPassengers and faresCollected to zero MuniBus() - default constructor. Initializes both totalPassengers and faresCollected to 0 MuniBus(int tp, double fc) - constructor which initializes totalPassengers to tp, faresCollected to fc ~MuniBus() - destructor. Prints out a message saying that the bus is being destroyed, and also prints out totalPassengers and faresCollected. Write the class declaration and implement all of the constructors, the destructor, and member functions. You do not need to demonstrate using your class or show output.
