Hello! Sachith try this code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
class Program
{
int top;
int[] stack = new int[100];
public void pop()
{
Console.WriteLine("{0}", stack[top--]);
}
public void push(char x)
{
if (top == 100 - 1)
{
Console.WriteLine("Stack is overflow");
}
else
{
stack[++top] = x;
}
}
public static void Main()
{
Program Obj = new Program();
string word = "Sri Lanka";
int len = word.Length;
char[] array = word.ToCharArray();
for (int i = 0; i < len; i++)
{
Obj.push(array[i]);
}
for (int i = 0; i < len; i++)
{
Obj.pop();
}
Console.ReadLine();
}
}
}

Replace your line

int[] stack = new int[100];

with

char[] stack=new char[100];

Because it's return integer value,to fix this problem,i used following code and solved it..
publicvoidpop()
{
Console.Write("{0}",(char)stack[top--]);
}
anyway thank you pankaj :)
