public partial class MainWindow : Window   

{   

public MainWindow()   

{   

InitializeComponent();   

}   

  

private void Button_Click_1(object sender, RoutedEventArgs e)   

{   

Button b = (Button) sender;   

tb.Text += b.Content.ToString();   

}   

  

private void Result_click(object sender, RoutedEventArgs e)   

{   

try   

{   

calculatePremium(p);   

}   

catch (Exception ex1)   

{   

tb.Text = "Your Result is displayed";   

}   

}   

private void Button_Click_2(object sender, RoutedEventArgs e)   

{   

Button b2 = (Button) sender;   

tb2.Text += b2.Content.ToString();   

}   

  

private void Result_click2(object sender, RoutedEventArgs e)   

{   

try   

{   

calculatePremium(p);   

}   

catch (Exception ex2)   

{   

tb2.Text = "Please Enter the value again!";   

}   

}   

public double calculatePremium(Person person) {

// Added base premium

double premium = 5000;

// Increase premium depending on age

if (person.getAge() >= 18) {

premium *= 1.1;

}

if (person.getAge() >= 25) {

premium *= 1.1;

}

if (person.getAge() >= 30) {

premium *= 1.1;

}

if (person.getAge() >= 35) {

premium *= 1.1;

}

if (person.getAge() >= 40) {

// Add 20% per 5 years above 40

int age = person.getAge() - 40;

while (age >= 5) {

premium *= 1.2;

age -= 5;

}

}

// Add gender specific adjustments

if (person.getGender() == Gender.MALE) {

premium *= 1.02;

}

}

  

}

}

return premium;

}

  

private void Off_Click_1(object sender, RoutedEventArgs e)   

{   

Application.Current.Shutdown();   

}   

  

private void Del_Click(object sender, RoutedEventArgs e)

private void R_Click(object sender, RoutedEventArgs e)   

{   

if (tb.Text.Length > 0)   

{   

tb.Text = tb.Text.Substring(0, tb.Text.Length - 1);
