Using the Queue Class in C# to Manage a String Queue

In this exercise, you need to create a string queue using the Queue class that already exists in the DotNet platform. The Queue class is an implementation of the queue data structure that follows the FIFO (First In, First Out) principle, where the first element to enter is the first one to exit. The purpose of this exercise is to familiarize yourself with using the Queue class in C# to manage data efficiently.

In this exercise, you will create an instance of the Queue class, add elements to the queue using the Enqueue method (to insert elements), and remove elements using the Dequeue method (to remove the first element). You will also use the Peek method to view the first element without removing it. Throughout the exercise, you will learn how to leverage the predefined functionalities of the Queue class to manage data queues easily and efficiently.

By completing this exercise, you will gain experience in handling queues using C# framework classes, which will enable you to apply them in projects where you need to process elements in an orderly and sequential manner, such as task management or workflow control.

Objective

1. Create an instance of the Queue class.
2. Add several string elements to the queue using the Enqueue method.
3. Display the first element without removing it using the Peek method.
4. Remove elements from the queue using the Dequeue method and display each removed element.
5. Check if the queue is empty after all elements have been dequeued.

Example C# Exercise

 Copy C# Code 
using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        // Create a queue to store string elements
        Queue queue = new Queue();

        // Add elements to the queue using the Enqueue method
        queue.Enqueue("Apple");
        queue.Enqueue("Banana");
        queue.Enqueue("Cherry");

        // Display the first element without removing it
        Console.WriteLine($"First element (Peek): {queue.Peek()}");

        // Remove elements from the queue and display each one
        Console.WriteLine($"Dequeued: {queue.Dequeue()}");
        Console.WriteLine($"Dequeued: {queue.Dequeue()}");

        // Display the first element again after dequeuing some elements
        Console.WriteLine($"First element after dequeuing (Peek): {queue.Peek()}");

        // Remove the last element
        Console.WriteLine($"Dequeued: {queue.Dequeue()}");

        // Check if the queue is empty
        Console.WriteLine($"Is the queue empty? {queue.Count == 0}");
    }
}

 Output

First element (Peek): Apple
Dequeued: Apple
Dequeued: Banana
First element after dequeuing (Peek): Cherry
Dequeued: Cherry
Is the queue empty? True
