C# Stack example
Let's see an example of generic Stack class that stores elements using Push() method, removes elements using Pop() method and iterates elements using for-each loop.
using System;
using System.Collections.Generic;
public class StackExample
{
public static void Main(string[] args)
{
Stack names = new Stack();
names.Push("Anil");
names.Push("Sunil");
names.Push("Nikhil");
names.Push("Nitin");
foreach (string name in names)
{
Console.WriteLine(name);
}
Console.WriteLine("Peek element: "+names.Peek());
Console.WriteLine("Pop: "+ names.Pop());
Console.WriteLine("After Pop, Peek element: " + names.Peek());
}
}
using System.Collections.Generic;
public class StackExample
{
public static void Main(string[] args)
{
Stack names = new Stack();
names.Push("Anil");
names.Push("Sunil");
names.Push("Nikhil");
names.Push("Nitin");
foreach (string name in names)
{
Console.WriteLine(name);
}
Console.WriteLine("Peek element: "+names.Peek());
Console.WriteLine("Pop: "+ names.Pop());
Console.WriteLine("After Pop, Peek element: " + names.Peek());
}
}
Output:
Anil
Sunil
Nikhil
Nitin
Sunil
Nikhil
Nitin
Peek element: Nitin Pop: Nitin After Pop, Peek element: Nikhil
