using System.Threading.Tasks;
using System.Windows.Forms;

namespace SquareRootDemo
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void btn_squareRoot_Click(object sender, EventArgs e)
{
  
int no;
double k=0, sq;
no = Convert.ToInt32(txtNumber.Text);
sq = no / 2;
while (sq!=k)
{
k = sq;
sq = (no / k + k) / 2;
}
lbl_Answer.Text = "Square root of " + no + " is " + sq;
}
}
}
