// HOMEWORK 1
//------------------------------------------------------------
// DUE DATE: Wednesday, 2/22/2006
//============================================================
// Modify the program below as follows
//
// 1) Add datafields to represent the address of an employee.
//
//    a) Modify the constructors so they properly initialize 
//       these new data fields
//
//    b) Modify the print function to print out the new address
//       information
//
//    c) Add a function to return the ZIP code of an employee
//
//    d) Change the main program, so that is prints out a list
//       of all employees who live in an area with ZIP code 12345
//       and gives them a $10000 raise
//
//    e) Change the program such that the first employee who lives
//       in ZIP-code 06660 will be fired
//
//
// 2) Answer the following questions in English:
//
//    a) What is the difference between a class declaration
//       and a class implementation?
//
//    b) What are constructors being used for and what do they need to do?
//
//    c) Please explain what the term "encapsulation" means (we will discuss
//       this during the lecture on Tuesday) and why it is useful
