For reference, this is Programming Problem Ch 10, #4 in Starting Out with Visual C# 2012 by Tony Gaddis.

The problem states "Design a class named Person with properties for holding a person's name, address, and telephone number. Next, design a class named Customer, which is derived from the Person class. The Customer class should have a property for a customer number and a Boolean property indicating whether a customer wishes to be on a mailing list. Demonstrate an object of the customer class in a simple application."

Currently, I've created seperate .cs pages for the Person Class and Customer Class. Also, I've created some code for Form.cs and will include how it displays. In the Form1 code, I'm not sure how to use the boolean mailing property, so in the current form1 code it is not used.

Also, I'm not sure how to turn the customer number output to display as a int. currently, the number that I enter will display. I'm really not sure if that is what is supposed to be done with this assignment.

Currently this is what displays:

When text is entered:

My code is as follows:

Customer.cs ("public string customerNumber" should be "public int customerNumber" but I couldn't get it to work with the Form's code)

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

namespace HW11CH10_4 { class Customer : Person { string _customerNumber; bool _mailing;

//customerNum property public string customerNumber { get { return _customerNumber; } set { _customerNumber = value; } }

//mailing property public bool Mailing { get { return _mailing; } set { _mailing = value; }

}

} }

Person.cs

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

namespace HW11CH10_4 { class Person { string _name; string _address; string _phoneNumber;

/ame property public string Name { get { return _name; } set { _name = value; } }

//address property public string Address { get { return _address; } set { _address = value; } }

public string phoneNumber { get { return _phoneNumber; } set { _phoneNumber = value; } } } }

Form1.cs

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms;

namespace HW11CH10_4 { public partial class Form1 : Form { public Form1() { InitializeComponent(); }

private void button1_Click(object sender, EventArgs e) { //object create for customer class Customer objcustomer = new Customer();

//set properties for customer class SetCustomerData(objcustomer);

//display customer properties label6.Text = objcustomer.Name; label7.Text = objcustomer.Address; label8.Text = objcustomer.phoneNumber; label9.Text = objcustomer.customerNumber.ToString();

}

private void SetCustomerData(Customer objcustomer) { //checks if name empty if (textBox1.Text != "") { //assigns object to text objcustomer.Name = textBox1.Text; } else { MessageBox.Show("Please Enter Customer Name"); }

//checks if address is empty if (textBox2.Text != "") { //assigns object to text objcustomer.Address = textBox2.Text; } else { MessageBox.Show("Please Enter Customer Address"); }

//checks if phone number is input if (textBox3.Text != "") { //assigns object to text objcustomer.phoneNumber = textBox3.Text; } else { MessageBox.Show("Please Enter Customer Phone Number"); }

//checks if cust number is input if (textBox4.Text != "") { //assigns object to text objcustomer.customerNumber = textBox4.Text; } else { MessageBox.Show("Please Enter Customer Number"); }

if (radioButton1.Checked) { label10.Text = "Customer wants to join mailing list"; }

else if (radioButton2.Checked) { label10.Text = "Customer does not want to join mailing list"; } }

private void button2_Click(object sender, EventArgs e) { this.Close(); } } }
