Data abstraction is a method to describe data in ways that help you decide what operations and encoding methods are available and also appropriate. Here, you don't need to understand how cout displays the text on the user's screen. The method of the abstract class that has no implementation is known as "operation". Data abstraction is the programming process of creating a data type, usually a class, that hides the details of the data representation in order to make the data type easier to work with. Hiding of data is known as data abstraction. - Definition & Examples, Describing the Relationship between Two Quantitative Variables, Making Estimates and Predictions using Quantitative Data, Binomial Distribution: Definition, Formula & Examples, Biological and Biomedical just create an account.
