Employee Class (Medium)
Write a class named Employee that has the following member variables:
name. A string that holds the employee’s name.
idNumber. An int variable that holds the employee’s ID number.
department. A string that holds the name of the department where the employee works.
position. A string that holds the employee’s job title.
The class should have the following constructors:
A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position.
A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string ("").
A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable.

(Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.
Employee and ProductionWorker Classes
Create an Employee class that has properties for the following data:
Employee name
Employee number
Next, create a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have properties to hold the following data:
Shift number (an integer, such as 1, 2, or 3)
Hourly pay rate
The workday is divided into two shifts: day and night. The Shift property will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2.
Create an application that creates an object of the ProductionWorker class and lets the user enter data for each of the object’s properties. Retrieve the object’s properties and display their values.
