Exercise #$2$

Write C$++$ program to maintain employee information for a business. There are two groups of employees, $$manager$$ and $$worker$.$ The suggested approach to complete the program is as follows:

$1.$ Declare a class $($using the name $$employee$)$ with the following data items

Employee Number: a $9-$digit integer number

Name: up to $30$ characters

Age: a $2-$digit integer number

Gender Code: single character

Education: two character code. For example HS$($High School$),$

AD$($Associate Degree$),$ CD$($Coll$.$ Degree$),$ MD$($Masters Degree$)$

$2.$ A worker class, which includes the above data items and has the following additional data items:

Hiring Date: in MM$/$DD$/$YYYY format

Dept. Name: $4$ characters, for example ACCT$($Accounting$),$ SALE$($Sales$)$

HUMN$($Human Resources$)$

Hourly Rate: float

$3.$ A manager class which includes the data items in class employee and has these additional data items:

Date of Promotion: in MM$/$DD$/$YYYY format

Department Name: $4$ characters

Job Title: $20$ characters

Yearly Salary: float

Your program should be menu$-$driven, such that when it starts, the main menu will display options such as: add manager, add worker, display manager, display worker, modify manger, modify worker.....etc. By selecting an option, corresponding function of different classes will be executed.

Limit the number of manager to $3$ and workers to $5$ such that if a user attempts to add $4$th manager a warning should be displayed informing the limit has been reached. Same with adding $6$th worker.
