Answer / narendra

The concept of abstraction relates to the idea of hiding
data that is not needed for presentation. The main idea
behind data abstraction is to give a clear separation

the user interface and the implementation details are
hidden. Thus, abstraction forms the basic platform for the
creation of user-defined data types called objects
