(CarbonFootprint Abstract Class: Polymorphism) Using an abstract class with only pure virtual functions, you can specify similar behaviors for possibly disparate classes. Governments andcompanies worldwide are becoming increasingly concerned with carbon footprints (annual releasesof carbon dioxide into the atmosphere) from buildings burning various types of fuels for heat, vehicles burning fuels for power, and the like. Many scientists blame these greenhouse gases for the phenomenon called global warming. Create three small classes unrelated by inheritance—classesBuilding, Car and Bicycle. Give each class some unique appropriate attributes and behaviors thatit does not have in common with other classes. Write an abstract class CarbonFootprint with onlya pure virtual getCarbonFootprint method. Have each of your classes inherit from that abstract classand implement the getCarbonFootprint method to calculate an appropriate carbon footprint forthat class (check out a few websites that explain how to calculate carbon footprints). Write an application that creates objects of each of the three classes, places pointers to those objects in a vectorof CarbonFootprint pointers, then iterates through the vector, polymorphically invoking each object’s getCarbonFootprint method. For each object, print some identifying information and the object’s carbon footprint.
