In this question we model a database of employees of a company. Assume that there are only two types of employees: labourers and managers. The database is to store a name, an employee number, a salary, and an employment start date for each employee. In addition, for labourers a department is stored, and for managers a title is stored. We will use a base class called employee and two derived classes: labourer, and manager, as shown in the following UML.

Implement the employee classes by declaring and defining all necessary function memebers based on the following main program.

Main Program Using Classes EmployeeTypes

$/*$ File: testemployeetypes.cpp

Application program using classes employeetypes
