Objective: Create a console$-$based Employee Management System that allows you to add, view, update,

and delete employee records. This project will help your students practice the concepts of classes,

inheritance, user interface, and event handling.

Project Structure:

Employee Class $($Base Class$)$:

Properties: Employee ID$,$ First Name, Last Name, Email, and Salary.

Methods: Constructor, GetDetails $($to display employee details$),$ and a virtual method CalculateSalary $($to

calculate salary$).$

FullTimeEmployee Class $($Inherited from Employee$)$:

Properties: Full$-$time employee$-$specific data $($e$.$g$.,$ Bonus$).$

Override the CalculateSalary method to calculate the salary for full$-$time employees $($base salary $+$

bonus$).$

PartTimeEmployee Class $($Inherited from Employee$)$:

Properties: Part$-$time employee$-$specific data $($e$.$g$.,$ HourlyRate, HoursWorked$).$

Override the CalculateSalary method to calculate the salary for part$-$time employees $($hourly rate $*$ hours

worked$).$

EmployeeRepository Class:

Create an EmployeeRepository class to manage employee records $($add$,$ view, update, delete$).$

Use a collection $($e$.$g$.,$ List$)$ to store employee objects.

User Interface $($Console Application$)$:

Create a menu$-$driven console application for interacting with the Employee Management System.

Options: Add Employee, View Employee, Update Employee, Delete Employee, and Exit.

Event Handling:

Implement event handling to log important actions like adding, updating, and deleting employees.

Create an event in the EmployeeRepository class and subscribe to it in the user interface.

Project Implementation Guidelines:

Create the necessary classes $($Employee$,$ FullTimeEmployee, PartTimeEmployee, EmployeeRepository$)$

with properties, methods, and event handling.

Implement the user interface with a menu system, where users can choose different actions.

Use exception handling to handle errors gracefully $($e$.$g$.,$ invalid input, employee not found$).$

Implement appropriate validation for user inputs $($e$.$g$.,$ validate email format, numeric inputs, etc.$).$

Ensure proper formatting of displayed data to make the user interface user$-$friendly.

Implement logging of actions using events $($e$.$g$.,$ when an employee is added, updated, or deleted$).$

Project Size: The project code should be around $300-400$ lines of code, but this can vary depending on

the level of detail and features you want to include.
