Introduction:
Data hiding, also known as encapsulation, is a fundamental concept in Object-Oriented Programming (OOP) that plays a pivotal role in maintaining the integrity and security of class attributes. In this comprehensive article, we will delve into the concept of data hiding, its importance, implementation, and real-world applications within OOP.
