Course Outline
Array is a collection of elements where the data types of all elements are the same. With the help of a C program, let’s understand what are arrays and how it works in the C language.
A linked list is a linear type of data structure that comes in handy while solving complex problems. This module gives a brief on the linked list along with discussing its advantages, disadvantages, and applications. You also have a demonstration on a linked list with the help of a code example.
Stack comes under a linear data structure and is known for its FILO/LIFO property. The module focuses on introducing you to stack and goes through its several advantages, disadvantages, and applications. You will also learn about its demonstration using an array with the help of a code example.
A queue is a linear form of data structure and follows the FIFO/LILO property. The module starts by giving you a brief on queue, its advantages, disadvantages, and applications. Lastly, you will have a demonstration of the queue using an array with the help of a code example.
A binary tree is a hierarchical and the most critical data structure. The course starts by familiarizing you with binary tree and binary search tree, their advantages, disadvantages, and applications. You will also have demonstrations of binary tree and binary search tree with the help of code examples.

Data Structures in C
In C, data structures are used to store information in a logical and efficient manner. Many data structures are available in the C programming language, such as an array, stack, queue, linked list, tree, and so on. A programmer chooses an acceptable data structure and applies it to their needs.
Let us look into some of these data structures:
-
Array
-
Stack
-
Queue
-
Linked List
-
Trees
-
Hashing
ARRAY
An array is a collection of elements with the same data type that are settled and arranged in a logical order. In memory, they are organized in sequential order. An array is a data structure that holds elements of the same type. In C, unlike in Java, array elements are not recognized as objects.
Imagine you're in a music store, and I order you to stack all of the Casio keyboards, one on top of the other. An Array is a collection of records that are arranged in a logical order. An array is a collection of elements of the same data type that are arranged in a logical order. Casio is the data type in our example, and all of the keyboards you collected are from the Casio brand. A common name is used to address all of the elements in an array.
There are two types of arrays:
-
Single dimensional array
-
Multidimensional array
Advantages :
1) Data Access Code Optimization: Less code is required to access the data.
2) Ease of traversal: We may quickly obtain the items of an array by utilizing the for a loop.
3) Sorting is simple: We simply need a few lines of code to sort the array's components.
4) Random Access: The array allows us to access any element at any time.
Disadvantages
- The size is set.
- Inserting and deleting data is difficult.
- If capacity is more than occupancy, the majority of the array is wasted.
- To be allocated, contiguous memory is required.
Applications
-
For storing info or data in a linear fashion
-
Suitable for applications that entail frequent searching
STACK
stack is a data structure that is linear. It employs the last in, first out strategy. At the top of a stack, a new item is added. From one end of the stack, both insert and delete operations are done.
Stacks are used for two different purposes. To add elements to the stack, use the push function, and to remove pieces from the stack, use the pop function.
Advantages
-
Maintains data in a LIFO style
-
The last element is readily obtainable for use
-
All operations are of O(1) complexity
Disadvantages
-
Manipulation is constrained to the top of the stack
-
Not very flexible
Applications
-
Recursion
-
Parsing
-
Browser
-
Editors
QUEUE
A Queue is a data structure that stores a collection of elements in a linear fashion. The queue follows the FIFO (first in, first out) principle. The first element added to an array is also the first element withdrawn from the array in queues.
When things don't have to be processed right away, but rather in a First In First Out manner, like a breadth-first search, a queue is utilized. Queue's property makes it handy in situations when a resource is shared by numerous customers.
Advantages
-
Maintains data in FIFO style
-
Insertion from the beginning and deletion from the end takes O(1) time
Applications
-
Scheduling
-
Maintaining playlist
-
Interrupt handling
LINKED LIST
A data structure is known as a Linked List. It follows a set of rules. The Linked List is similar to an array, except it is not maintained in memory in sequential order. Every linked list has two sections: the data section and the address section, which contains the address of the next node in the list.
The linked list's size isn't predetermined, and data items can be added at any point along the way. The drawback is that in order to reach a node, we must go from the initial node to the desired node.
There are three types of link lists:
-
Singly link list
-
Doubly link list
-
Circular link list
Advantages of Data Structure using C
-
Adjustable in size.
-
There is no waste because capacity and size are always equal.
-
Simple insertion and deletion due to only one link change
-
Memory allocation is efficient.
Disadvantages of Data Structure using C
-
If the head node vanishes, the linked list is lost.
-
No random access is feasible.
Applications of Data Structure using C
-
Suitable where memory is inadequate.
-
Suitable for applications that necessitate frequent insertion and deletion.
TREES
A tree is a data structure with numerous sub-nodes and a single root node. Another data structure built on top of a linked list is the linked list.
Advantages
-
Data/Info can be represented as a relationship.
-
Insertion and search are significantly faster.
Disadvantages
-
Sorting is grim
-
Not much supple
Applications
-
File system grading or hierarchy
-
Multiple dissimilarities of the binary tree have a wide variety of applications
HASHING
Another type of data structure is the hash table. It's used to make an associative array, which is a type of data structure that can map keys to values. A hash table computes an index into an array of buckets using a hash function. Hash tables are a type of data structure that is extremely helpful.
Advantages
-
The hash function aids in fetching elements in constant time
-
A well-organized way to store elements
Disadvantages
- Collision resolution upsurges complexity
Applications
- Suitable for the application desires constant time fetching
