What Is an Abstract Data Type?

Abstract data types (Abtracttract Data , ADT ) are mathematical models of specific types of data structures in computer science that have similar behavior; or data types of one or more programming languages with similar semantics. Abstract data types are defined indirectly through the mathematical operations (and possible costs) that can be performed on them and the effects of those operations.

Abstract Data Type ( A bstract D ata Type , ADT ) is

In programming languages (or libraries) and textbooks, several common abstract data types are as follows:

• When implemented in a program, the abstract data type only exposes its interface and hides the implementation. The user only needs to care about its interface, not how to implement it. The future can change the way it is implemented. (Its support

  Abstract data structure is based on the data to be calculated and its

  Some abstract data types are quite common and practical in programming, so in some programming languages, they become native types or are added to the standard library. For example, Perl arrays can be implemented with abstract data types such as lists or deques, and hash tables can also be implemented with Map or Table. The C ++ standard library and Java library also provide lists, stacks, queues, Maps, priority queues, and strings. ^[1]
