Answer to Question #212505 in Electrical Engineering for ali

Question #212505

Create three classes —House, Car and Mobile.

o House class should have attributes of area and location. 

o Car class should have attributes of color and registration number.

o Mobile class should have attribute of model. 

o Write an abstract class PollutionEffect with only a pure virtual getPollutionEffect method. 

o Each of the three classes should inherit from this abstract class and implement the 

getPollutionEffect method to print an appropriate pollution effect count for that class. 

o The getPollutionEffect of House class should print “one”, Car class should print “Two” and 

Mobile class should print “Three”.

o Write an application that creates objects of each of the three classes, places pointers to those 

objects in a array of PollutionEffect pointers, then iterates through the array, invoking each 

object’s getPollutionEffect method.
