Answer / purush
A unique datatype, that is defined by the progrmer.It may
refer to an object class in OOP or to a special data type in
traditional,non-OOP languages.
ADT is a specification of a set of data and the set of
operations that can be performed on the data.This supports
the principle of INFORMATION HIDING.
