Queue in C is a data structure that is not like stack and one can relate the behavior of queue in real -life. Unlike stack which is opened from one end and closed at the other end which means one can enter the elements from one end only. Therefore, to overcome the scenario where we...
Queue Complete ImplementationFollowing are the complete implementations of Queue in various programming languages −C C++ Java Python Open Compiler #include <stdio.h> #include <string.h> #include <stdlib.h> #include <stdbool.h> #define MAX 6 int intArray[MAX]; int front = 0; int rear ...

C programming language implementation of the isempty() function − bool isempty() { if(front < 0 || front > rear) return true; else return false; } Enqueue Operation Front and rear data pointers are kept in queues. As a result, compared to stack operations, its operations are more co...

This post will discuss how to implement queue data structure in JavaScript. A queue is a data structure that follows the principle of First In First Out (FIFO).
This article covers queue implementation in Java. A queue is a linear data structure that follows the FIFO (First–In, First–Out) principle. That means the object inserted first will be the first one out, followed by the object inserted next. ...
Queue Implementation using Two Stacks in C++:Here, we are going toimplement a C++ program to implement Queue using two Stacks. Submitted byRadib Kar, on September 25, 2018 Queue: A queue is a data structure for storing data where the order in which data arrives is important. The queue is...
