Completed Order Example

Project Overview

This assignment expanded on basic Windows Forms skills by combining user input, conditional UI, and pricing logic into a single form. The app collects the customer's name and, if delivery is selected, prompts for address and phone number. It then allows the user to configure the pizza: pickup or delivery, crust type, size, cheese options, and toppings.

Once the choices are made, the application calculates the total price and displays an order summary. This provides a simple but realistic flow for ordering a pizza and demonstrates how UI controls and business logic can work together.

Key Logic (Order Summary & Pricing)

A simplified example of how the total and summary might be built:

private void btnPlaceOrder_Click(object sender, EventArgs e)
{
    decimal total = 0m;

    // Base price from size
    if (radSmall.Checked)  total += SMALL_PRICE;
    if (radMedium.Checked) total += MEDIUM_PRICE;
    if (radLarge.Checked)  total += LARGE_PRICE;

    // Crust and toppings
    if (radDeepDish.Checked) total += DEEP_DISH_UPCHARGE;

    if (chkPepperoni.Checked) total += TOPPING_PRICE;
    if (chkMushrooms.Checked) total += TOPPING_PRICE;
    if (chkOnions.Checked)    total += TOPPING_PRICE;

    // Delivery charge
    bool isDelivery = radDelivery.Checked;
    if (isDelivery)
        total += DELIVERY_FEE;

    string summary = $"Customer: {txtName.Text}\n" +
                     $"Type: {(isDelivery ? "Delivery" : "Pickup")}\n" +
                     $"Total: {total:C}";

    txtSummary.Text = summary;
}

The actual project uses the specific controls defined on the form, but the idea is the same: determine a base price from size and crust, add charges for toppings and delivery, then present a readable order summary.

What I Learned

• How to design a multi-section Windows Forms UI that handles customer info and configuration options.
• How to use radio buttons and checkboxes to drive pricing logic in C#.
• How to conditionally show or require extra fields (like address and phone) for delivery orders.
• How to build a clear summary string that confirms the customer's selections and total cost.
