Queue Implementation Using an Array

There are multiple ways to implement a queue data structure. Let’s look at how we can implement a queue using an array data structure. First, we create an array called data of size capacity. Then, we make two variables front and back. Initially, the size of the queue is 0. The Enqueue() function is used to add elements at the back of the queue using the back variable, while the Dequeue() function is used to remove elements from the front of the queue using the front variable.
