  11. // Description: An object oriented program design using
  12. // C++ that will process our existing set of employees.
  13. // It utilizes a class called Employee and generates an 
  14. // array of objects that are used to store, calculate,
  15. // and print out a simple report of inputted and calculated
  16. // values.
  17. //
