//
// Description: An object-oriented program design using
// C++ that processes a set of employees.
// It utilizes a class called Employee and generates an 
// array of objects that are used to store, calculate,
// and print out a simple report of inputted and calculated
// values.
//
// Object-Oriented Design (using C++)
