Program to peek elements from Queue C#

using System;
using System.Collections;

namespace ConsoleApplication1
{
    
    class Program
    {
        static void Main()
        {
            Queue Q = new Queue(5);

            Q.Enqueue(10);
            Q.Enqueue(20);
            Q.Enqueue(30);
            Q.Enqueue(40);

            
            Console.WriteLine("Peeked item: " + Q.Peek());
            Console.WriteLine("Peeked item: " + Q.Peek());
            Console.WriteLine("Peeked item: " + Q.Peek());
            Console.WriteLine("Peeked item: " + Q.Peek());

        }
    }
}

Output

Peeked item: 10
Peeked item: 10
Peeked item: 10
Peeked item: 10

In this program, we are inserting 4 items into queue, then getting items from queue without removing them, using Peek() method, so that we always got same item.

Note: In above program, to use 'Queue' class, we need to include System.Collection namespace.
