Understanding Object-Oriented Design: Class Relationships and Code Reusability

This guide delves into essential concepts of Object-Oriented Programming (OOP), focusing on class relationships such as "Has-a" and "Is-a" relationships. It explains the principles of inheritance, contrasting private and protected access modifiers and their implications on derived classes. Using the classic example of an Employee class, we explore how to effectively implement reusability through constructors and member initialization lists. Enhance your OOP skills by mastering these foundational concepts.
