Abstract data type is a mathematical model with a collection of operations defined on that model.

1. Abstract Data Types

2. Abstract Data Type
• Model of a data type
• Properties of the data
• Operations that can be performed on that data
• Definition: Abstract data type (ADT) is a
mathematical model with a collection of
operations defined on that model.

4. One more Example of ADT
• SET
• {2,4,6,8,10}
• Take two SET as input and return union
• SET union(SET a, SET b)
• Take two SET as input and return intersection
• SET intersection(SET a, SET b)
• Take two SET as input and return difference
• SET difference(SET a, SET b)
SET ADT
Properties
- Group of elements
Operations
• Union
• Intersection
• Difference

5. Implementation of ADT
• Implementation of an ADT means writing a program in a
programming language.
• Data structure deals with the implementation of various ADTs.
• In this course we will examine mathematical model of various data
types and implement those using C programming language.
