Graph Abstract Data Type In Data Structures

In computer science an abstract data type is a mathematical model for data types. An abstract data type is defined by its behavior from the point of view of a user of the data specifically in terms of possible values possible operations on data of this type and the behavior of these operations. If we consider a composite type such as a string it describes a data structure which contains a sequence of char primitives characters and as such is referred to as being a composite type.

Data type that is defined by its behaviour tuple set stack queue graph etc.

Graph abstract data type in data structures. Graph is used to implement the undirected graph and directed graph concepts from mathematics. It is a pictorial representation of a set of objects where some pairs of objects are connected by links. Abstract data types commonly abbreviated adts are a way of classifying data structures based on how they are used and the behaviors they provide.

Addvertexvert adds an instance of vertex to the graph. The graph abstract data type adt is defined as follows. Graph creates a new empty graph. Addedgefromvert tovert adds a new directed edge to the graph that connects two vertices.

Getvertexvertkey finds the vertex in the graph named vertkey. Abstract data type adt is a type or class for objects whose behaviour is defined by a set of value and a set of operations. A graph data structure consists of a finite and possibly mutable set of vertices also called nodes or points together with a set of unordered pairs of these vertices for an undirected graph or a set of ordered pairs for a directed graph. It signifies the type like integer float etc the space like integer will take 4 bytes character will take 1 byte of space etc.

The definition of adt only mentions what operations are to be performed but not how these operations will be implemented. Graph is an abstract data type. Addedgefromvert tovert weight adds a new weighted directed edge to the graph that connects two vertices. The data type is basically a type of data that can be used in different computer program.

This mathematical model contrasts with data structures which are concrete representations of data and are the point of view of an implementer not a user. They do not specify how the data structure must. Formally an adt may be defined as a clas. It represents many real life application.

They do not specify how the data structure must. The abstract datatype is special kind of datatype whose behavior is defined by a set of values and set of operations. In computer science a graph is an abstract data type that is meant to implement the undirected graph and directed graph concepts from the field of graph theory within mathematics.
