C# Program to Implement Stack with Push and Pop operations
Set stack with Push operation to add elements to the Stack −
Stack st = new Stack(); st.Push('A'); st.Push('M'); st.Push('G'); st.Push('W');
To Pop elements from the stack, use Pop() method −
st.Pop();
st.Pop();
The following is an example to implement a stack with Push and Pop operations −
Example
using System; using System.Collections; namespace CollectionsApplication { class Program { static void Main(string[] args) { Stack st = new Stack(); st.Push('A'); st.Push('M'); st.Push('G'); st.Push('W'); Console.WriteLine("Current stack: "); foreach (char c in st) { Console.Write(c + " "); } Console.WriteLine(); st.Push('V'); st.Push('H'); Console.WriteLine("The next poppable value in stack: {0}", st.Peek()); Console.WriteLine("Current stack: "); foreach (char c in st) { Console.Write(c + " "); } Console.WriteLine(); Console.WriteLine("Removing values "); st.Pop(); st.Pop(); st.Pop(); Console.WriteLine("Current stack: "); foreach (char c in st) { Console.Write(c + " "); } } } }
Output
Current stack: W G M A The next poppable value in stack: H Current stack: H V W G M A Removing values Current stack: G M A
