Question #344578

Task 3:

Consider a class Computer having Two fields (i.e. companyName, price) and A single function named show() A class named Desktop inherits Computer class and adds fields representing color, monitor size, and processor type and Override function named show() to display values of its all attributes A class named Laptop inherits Computer class and adds fields representing color, size, weight, and processor type and Override function named show() to display values of its all attributes In Main() instantiate objects of derived classes to access respective show() functions to see the polymorphic behavior.
