Programs incorporating data hiding are segregated into objects with specific data and functions. However, you couldn't create a running shoe from the "cat" class because the latter lacks the characteristics needed to create a shoe. Carrying this idea over to Java, the “cat” class is a blueprint we can use to generate any individual cats that include all cat characteristics (e.g., eye shape, tail length, fur color). For instance, a specific housecat is an object in the class of “cats.” The world’s cats share some characteristics from the same template (e.g., they have whiskers and tails, and they are felines). Data hiding guarantees exclusive data access to class members only and protects and maintains object integrity by preventing intended or unintended changes and intrusions.Ĭlasses are groups of objects that share common properties or behaviors. What Does Data Hiding Mean?ĭata hiding is an object-oriented programming (OOP) technique specifically used to hide internal object details (i.e., data members). So, we begin by establishing exactly what data hiding in C++ is. Finally, we'll round out the pros and cons of data hiding and its practical applications. Additionally, we'll learn the difference between data hiding, data abstraction, and data encapsulation. We are about to learn about data hiding in C++, including its definition, private and public members and methods, and protected members and methods. What’s one of the best ways to ensure that no one gets their hands on your personal property? You hide it!Īnd that's what we will be learning about here today.
