Project Description

This project is designed for new learners of OOP. You can fork this project and complete the missing parts according to given descriptions. After completing this project, you will learn OOP programming and its principles.

In this project we have 3 classes: (Employee, SoftwareDeveloper, Manager) and 3 interfaces (IEmployee, ISoftwareDeveloper, IManager). You should implement these 3 classes and 3 interfaces according to given conditions:

1. Employees have id, firstName, lastName, age, salary, and department attributes. Employees can take a break and can get salary payments.
2. Managers are also employees and additionally have employees attribute and can hire or fire employees and increase salaries.
3. Software Developers are also employees and additionally have skilss, supervisor, and experience attributes. They can write and test code, and push the changes.

The template of the classes and interfaces are given with descriptions. Please fill the missing parts.
