Mar 12, 2025 · To implement a queue of size n using an array, the operations are as follows: Enqueue: Adds new elements to the end of the queue. Checks if the queue has space before insertion, then increments the size. Dequeue: Removes the front element by shifting all remaining elements one position to the left. Decrements the queue size after removal.

May 27, 2024 · In this article, we will learn how to implement a Queue using Array in C. To implement Queue using Array in C, we can follow the below approach: Define a structure consisting of an array and two pointers front and rear. Initialize the array with MAX_SIZE. Initialize both the front and rear pointers to -1.

Mar 5, 2025 · Queue is a linear data structure that follows FIFO (First In First Out) Principle, so the first element inserted is the first to be popped out. FIFO Principle in Queue: FIFO Principle states that the first element added to the Queue will be the first one to be removed or processed.

Queue operations work as follows: We usually use arrays to implement queues in Java and C/++. In the case of Python, we use lists. self.k = k. self.queue = [None] * k. self.head = self.tail = -1 # Insert an element into the queue def enqueue(self, data): if (self.tail == self.k - 1): print("The queue is full\n") elif (self.head == -1):

Mar 17, 2025 · We can easily represent queue by using linear arrays. There are two variables i.e. front and rear, that are implemented in the case of every queue. Front and rear variables point to the position from where insertions and deletions are performed in a queue. Initially, the value of front and queue is -1 which represents an empty queue.

Jul 23, 2024 · Learn queue implementation using arrays in the data structure and execution of supportive queue operations in this tutorial. Start learning now!

Queue data structure using array can be implemented as follows... Before we implement actual operations, first follow the below steps to create an empty queue. Step 1 - Include all the header files which are used in the program and define a constant 'SIZE' with specific value.

Jan 15, 2025 · To implement queues in data structures, arrays, and linked lists are commonly used, with array queues in data structures being one of the fundamental implementations. In this DSA tutorial, we will examine thequeue data structurein detail, including its features, workings, implementation, etc.

Queue implements the FIFO mechanism i.e., the element that is inserted first is also deleted first. In other words, the least recently added element is removed first in a queue. A program that implements the queue using an array is given as follows ? cout<<"Queue Overflow"<<endl; else { if (front == - 1) . front = 0; .

As a small example in this tutorial, we implement queues using a one-dimensional array. Queue operations also include initialization of a queue, usage and permanently deleting the data from the memory. The most fundamental operations in the queue ADT include: enqueue (), dequeue (), peek (), isFull (), isEmpty ().
