What is ADT? (Abstract Data Type)

Question

I am currently studying about Abstract Data Types (ADT\'s) but I don\'t get the concept at all. Can someone please explain to me what this actually is? Also what is collecti

Answer 1

Abstract data type are like user defined data type on which we can perform functions without knowing what is there inside the datatype and how the operations are performed on them . As the information is not exposed its abstracted. eg. List,Array, Stack, Queue. On Stack we can perform functions like Push, Pop but we are not sure how its being implemented behind the curtains.
