Introduction

Data structure using c provides efficiency, reusability, and abstraction. It plays an essential role in enhancing a program’s performance because its primary function is to store and retrieve the user’s data as fast as possible.

The C Programming language has various data structures like an array, stack, queue, linked list, tree, etc. A programmer chooses an appropriate data structure and uses it according to their convenience.

The Data Structure and the algorithm synthesis are related to each other. Data presentation must be simple to understand so the developer and the user can make a capable implementation of the operation.

What is Data Structure?

In Data Structure Using C, the data structure is a storage familiar with the store and organizing data. It is arranging data on a computer to be retrieved and updated effectively.

A data structure is meant for more than just organizing the data. It is also intended for processing, retrieving, and storing data. Almost every program or software system uses different basic and advanced types of data structures.

Importance Of Data Structure

In Data Structure Using C,the Data Structure and the algorithm synthesis are related to each other. Data presentation must be simple to understand so the developer and the user can make a capable implementation of the operation.

Data structures allow a simple method of organizing, retrieving, managing, and storing data.

Here are some needs for data.

• Data structure modification is easy. 
• It requires less time. 
• Save storage memory space. 
• Data representation is straightforward. 
• Easy access to the extensive database.

What is Data Structure using c?

Data Structures using C are familiar with storing data in an organized and efficient manner. The C Programming language has various data structures like an array, stack, queue, linked list, tree, etc. A programmer chooses an appropriate data structure and uses it according to their convenience.

Why is Data Structures in C Important?

Data structure using c  provides efficiency, reusability, and abstraction. It plays an essential role in enhancing a program’s performance because its primary function is to store and retrieve the user’s data as fast as possible.

Types of Data Structure using C

The data structure has many different uses in our daily life. Many other data structures are used to solve various mathematical and logical problems.

The data structures in C can be categorized into two:

Primitive Data Structures

In Data Structure Using C, the primitive data structures using C are those basic data structures already specified in the C language. These data structures can be familiar with the store of only a single value. They are the foundation of data manipulation. The primitive data structures in C include int, char, float, double, and pointers.

Non-Primitive Data Structures

In Data Structure Using C, the non-primitive data structures in C are also known as the derived data structures, as they are derived from primitive ones. A large number of values can be stored using non-primitive data structures. The data stored can also be manipulated using various operations like insertion, deletion, searching, sorting, etc. Data structures like arrays, trees, stacks, and many more come under this category.

The non-primitive data structures in C can further be divided into two categories:

Linear data structure:

In Data Structure Using C, the data structure in that data elements are arranged serially or linearly, where each element is connected to its previous and next close elements, is called a linear data structure. 

Some examples of Linear data structures are array, stack, queue, linked list, etc.

Static data structure:

 The static data structure has a permanent memory size. It is simpler to obtain the elements in a static data structure. 

Data Structure is an array.

Dynamic data structure

The dynamic data structure has a flexible memory size. It can be randomly up to date during the runtime, which may be considered efficient concerning the code’s memory (space) complexity. Examples of Dynamic data structures are queues, stacks, etc.

Non-linear data structure:

 Data structures where data elements are unplaced serially are called non-linear data structures. In a non-linear data structure, we can’t cross all the elements in a single run. 

Arrays:

In Data Structure Using C, the array is a linear data structure, a collection of items stored at contiguous memory locations. The idea is to keep multiple items of the same type together in one place. It allows processing a large number of data in a relatively brief period. The element of the array is indexed by a subscript of 0. Different operations are possible in an array, like Searching, Sorting, Inserting, Traversing, Reversing, and Deleting.

 Applications of Array: 

• An array is often used to store data for mathematical computations.
• It is used in image processing.
• It is also used in record management.

Linked list: 

In Data Structure Using C, the linked list, a linear data structure in which elements are not stored at contiguous memory locations. 

They can be stored anywhere in the memory and are not connected adjacently. We have to use a pointer to link the elements together.

The pointer heads a linked list to the first node, the head node. The head node or head does not contain any value, but it stores the address of the first element of the list.

Syntax

// A linked list node

struct Node {

   int data; // data of the node

   struct Node* next;

};

Applications of the Linked list: 

 Applications of linked lists are,

• Linked lists are acclimated to implement stacks, queues, graphs, etc.
• Linked lists are familiar with performing arithmetic operations on long integers.
• It is intended for the representation of sparse matrices.
• It is applied in the linked allocation of files.

Stack: 

In Data Structure Using C, the stack, a linear data structure that follows a particular order in which the operations are performed. The order is LIFO. Entering and retrieving data is viable from only one end. recursion in data structure, The entering and retrieving of data are also called push and pop operations in a stack. data structure using c, Different operations are likely
in a stack, like reversing a stack using recursion, Sorting, deleting a stack’s central element, etc. 

Syntax

struct stack

{

   int myStack[capacity];

   int top;

};

Applications of Stack: 

• A stack is a level of eating plates arranged above each other. While you remove a plate from the pile, you can take the plate to the top of the pile. But this is precisely the plate added most lately to the pile. If you demand the plate at the bottom of the pile, you must eliminate all the plates on top of it to reach it. 
• Browsers apply stack data structures to keep track of formerly visited sites.
• Call log-in mobile also uses the stack data structure.

Queue: 

In Data Structure Using C, the queue is a linear data structure that follows a particular order in which the operations are performed. data structure using c, The order is FIFO, i.e., the stored data item will be accessed first. In this, entering and retrieving data is done from multiple ends—any queue of consumers for a resource, wherever the consumer that came first is served first.

Syntax

struct Queue {

   int myQueue[capacity]; 

   int front, rear;

};

 Applications of Queue: 

• A queue is a single-lane one-way road, wherever the vehicle entering will exit first. 
• A real-world example can seen in the queue at the ticket windows.
• A cashier line in a store is an example of a queue.

Tree:

In Data Structure Using C,the tree a non-linear and hierarchal data structure wherever the elements are arranged in a tree-like configuration. In a tree, the highest node is called the root node. Each node stores some data, and data can be of any type. data structure using c, It contains a central node, structural nodes, and sub-nodes linked via edges. Different tree data structures permit quicker and easier access to the data as it is non-linear.

Applications of Tree: 

• Tree data structure helps in Game Development. 
• It helps in indexing databases. 
• A Decision Tree is a capable machine-learning tool generally used in decision analysis.
• Domain Name Server uses a tree data structure.

Graph:

In Data Structure Using C, the graph is a non-linear data structure including vertices and edges. It compromises a finite set of vertices and edges related to a pair of nodes. The graph is acclimated to solving the most challenging and complex programming problems. 

Syntax

struct Queue {

   int myQueue[capacity]; 

   int front, rear;

};

 Applications of Graph: 

• The most common example of a graph is Google Maps, wherever cities are located, and paths linking those vertices are placed as edges of the graph.
• A social network is also one example of a graph where every person on the web is a node, and all their friendships are the graph’s edges.
• A graph is used to study molecules in physics and chemistry.
