**Data structure in c** is a way of storing data in a computer or device. So that data can be used **effectively **and **easily**.

That is, a data structure is a way of** storing data** so that data can be accessed easily.

## What is Data Structure in C

The type of data structure in c language is followed by something like this -

**Array****Queue****Stack****Linked list****Tree**

Following this type, the outline of the program is displayed.

## Roll of Data Structure in C

- How is data saved in memory
- Which are the ways in which data can be stored
- How many ways data can be obtained, and can be changed.
- Knowing the
**simplest**way, the data structure is a way of**organizing data**.

## Uses of Data Structure in C

## 1.Array

The array is a linear data structure. All the data item in an array is **stored **at the **consecutive memory locations **of the RAM.

All elements of the array are the same data type. And the name of the array is defined at the time of **declarations**.

Example - In the following example, there are 5 classes, in which students are shown from the array.

In this example, the name of the class array is and the position of the item is from a square bracket. Which starts from zero.

**Type of Array **

**1.Single Dimensional Array**

An array containing a liner list of data items. In which the storage of data is only at the memory locations located nearby.

**2.Multidimensional-Array**

__Example of Array__

#include <stdio.h>

int main () {

int class [5];

printf ("Enter 5 numbers:");

for (int a = 0; a <5; ++ a)

{

scanf ("% d", & class [a]);

}

printf ("display inter number:");

for (int a = 0; a <5; ++ a)

{

printf ("% d \ n", class [a]);

}

return 0;

}

### 2.Stack

A stack is a linear data structure. The stack follows the **LIFO **approach, ie last in first out or first in last out (**FILO**). In which whatever last data item is added is at the top of the stack.

The stack performs two operations: insertion and deletion operations in which data is inserted and removed.

### 3.Queue

The queue is also a linear data structure Queue **FIFO **(first in first out) or **LILO **(last in last out)Approach follows.

The queue has two ends, front and rear, which contain insert and remove data.

The queue has two operation performances: insertion and deletion

### 4.Linked list

A linked list is a data structure that consists of a collection of nodes. It consists of **two nodes**. Each node contains information. One node contains **data **and one contains the **address **of the next node.

Info is an information or **data store** in this field.

A link is the address of the next node in the link. If we get the address of one node, then we can find out about the address of the remaining node.

**Linked list types**

- Single linked list
- Doubly linked list
- circular linked list
- circular doubly linked list

### 5.Tree

The tree is the data structure in which the collection of nodes is done, the first node of the tree is called the root node and the remaining nodes are divided into sub-trees. Branches connect these nodes.

The tree data structure consists of a collection of the root, left sub-tree and right sub-tree.

Normal tree consists of two general tree and binary tree
