This document discusses data structures and their importance in program design. It defines a data structure as a specialized format for organizing and storing data for a specific purpose. The document outlines different types of data structures, including primitive structures like integers and characters that are directly operated on by the machine, and non-primitive structures like arrays, records, tables, and trees that are built from primitive structures. It also lists some common operations on data structures such as creation, selection, updating, searching, sorting, and deleting.

2. INTRODUCTION OF DS
 Data structure affects the design of both structural &
functional aspects of a program.
 Program=algorithm + Data Structure
 You know that a algorithm is a step by step procedure to
solve a particular function.

3. DATA STRUCTURE
 A data structure is a specialized format for
organizing and storing data.
 Different types of data structures include array file
record table and tree etc.
 Any data structure is designed to organize data for
a specific purpose.
 A data structure help the user to store data in such
a way that it can be used and processed efficiently.

4. DATA STRUCTURE OPERATIONS
 Some important operations on data structures are
as follows:
Create
Selection
Updating
Searching
Sorting
Deleting

5. TYPES OF DATA STRUCTURES:
 There are two types of data structure are as
follows:
Data structure
Primitive data structure Non primitive data structure

6. PRIMITIVE DATA STRUCTURE:
 There are basic structures and directly operated upon by
the machine instructions.
 In general, there are different representation on different
computers.
 Integer, Floating-point number, Character constants,
string constants, pointers etc, fall in this category

7. NON PRIMITIVE DATA STRUCTURE:
 There are more sophisticated data structures.
 These are derived from the primitive data structures.
 The non-primitive data structures emphasize on
structuring of a group of homogeneous (same type) or
heterogeneous (different type) data items

8. DIFFERENT BETWEEN PRIMITIVE AND NON
PRIMITIVE DATA STRUCTURE
 A primitive data structure is generally a basic structure
that is usually built into the language, such as an integer,
a float.
 A non-primitive data structure is built out of primitive
data structures linked together in meaningful ways, such
as a or a linked-list, binary search tree, AVL Tree, graph
etc.
