May 8, 2024 · In this article, we'll learn how to implement the queue data structure in the C programming language. We will also look at some of its basic operations along with their time and space complexity analysis. We can implement a queue in C using either an array or a linked list.

Apr 7, 2025 · A Queue Data Structure is a fundamental concept in computer science used for storing and managing data in a specific order. It follows the principle of "First in, First out" (FIFO), where the first element added to the queue is the first one to be removed. It is used as a buffer in computer systems

We can implement the queue in any programming language like C, C++, Java, Python or C#, but the specification is pretty much the same. A queue is an object (an abstract data structure - ADT) that allows the following operations: Queue operations work as follows: We usually use arrays to implement queues in Java and C/++.

What is a Queue? A queue is a linear data structure where elements are stored in the FIFO (First In First Out) principle where the first element inserted would be the first element to be accessed. A queue is an Abstract Data Type (ADT) similar to stack, the thing that makes queue different from stack is that a queue is open at both its ends.

Aug 3, 2022 · A queue in C is basically a linear data structure to store and manipulate the data elements. It follows the order of First In First Out (FIFO). In queues, the first element entered into the array is the first element to be removed from the array.

Mar 29, 2022 · Enqueue- adding an element in the queue if there is space in the queue. Front- get the first item from the queue. Rear- get the last item from the queue. isEmpty/isFull- checks if the queue is empty or full. Applications. A queue is used in scheduling processes in a CPU. It is used in data transfer between processes.

We can implement the queue data structure in C using an array. We add an element to the back of the queue, whereas we remove an element from the front of the queue. Therefore we need two pointers: head and tail to track the front and the back of the queue.

From simple linear queues to more advanced circular and priority queues, understanding their differences is key to selecting the right one for your application. Let explain its major types. 1. Simple Queue (Linear Queue)

Apr 28, 2023 · In C, we can implement a queue using an array or a linked list. For simplicity, we’ll use an array in our example. Note that this example uses structures and pointers. Let’s define a structure for our queue: int data[MAX_SIZE]; int front; int rear;

Jun 19, 2023 · A queue is a linear data structure in the C language that adheres to the FIFO (First In, First Out) rule. Arrays or linked lists can be used to implement it statically or dynamically. In...
