Hi,

using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Stack sk = new Stack();
Stack sk2 = new Stack();
foreach (int i in new int[4]{ 1, 2, 3, 4 })
{
sk.Push(i);
sk2.Push(i);
}

foreach (int i in sk)
{
Console.WriteLine(i);
}

sk.Pop();
Console.WriteLine("Pop");
foreach (int i in sk)
{
Console.WriteLine(i);
}

sk2.Peek();


Console.WriteLine("Peek");
foreach (int i in sk2)
{
Console.WriteLine(i);
}

while (sk2.Count != 0)
{
int i = (int)sk2.Pop();
sk2.Pop();
}
Console.WriteLine("clear");
foreach (int i in sk2)
{
Console.WriteLine(i);
}
}
}
}
