Features with stack in C#:

Creating a Stack:

You need to import the System.Collections.Generic namespace to work with the Stack. To create a Stack, you can use the following code:

Example

using System;
using System.Collections.Generic;
Stack<int> stackfruitprices = new Stack<int>();
Stack<string> stackfruitnames = new Stack<string>();

Pushing Elements:

You can add elements to the top of the Stack using the Push method:

Example

stackfruitprices.Push(12);
stackfruitprices.Push(16);
stackfruitprices.Push(22);
stackfruitprices.Push(28);
stackfruitprices.Push(9);
stackfruitnames.Push("Apple");
stackfruitnames.Push("Mango");
stackfruitnames.Push("Cherry");
stackfruitnames.Push("Orange");
stackfruitnames.Push("Grape");
stackfruitnames.Push("Kiwi");
