Part I:   The Employee Class

You are to first update the Employee class to include two virtual functions. This will make the Employee class an abstract class.

* Update the function display() to be a virtual function

    * Add function, double weeklyEarning() to be a pure virtual function. This will make Employee an abstract class, so your main will not be able to create any Employee objects.

Part II: The Derived Classes

Add an weeklyEarning() function to each of the three derived classes. A salaried employee’s weekly earning is as stored. An hourly employee’s weekly earning is the hrsworked * payperhr. A commissioned employee’s weekly earning would be the base + the comAmount.
