Question

Create an order entry screen program in C# to give a total for an individual pizza order. The Pizza order should have radio buttons for small $7, medium $9, and large $12 choices for the pizza. There should be a checkbox for drink (where a drink is $2 added if it is checked and nothing added if it is not checked. Include a textbox for the customer’s name. Have a button to calculate the subtotal (pizza choice and whether there is a drink or not on the order), tax (.07 of the subtotal) and the total (subtotal plus tax). Put these calculated values into labels on the screen for the user. Also have another label show a message to show the customer’s pizza is ready with their name from the textbox. Include a button to clear the order, it should clear the textbox, set the radio buttons back to having the large one selected, the checkbox for the drink should be unchecked, and textbox and the message label should be cleared. Make sure to rename the buttons and the output labels, they should not be named “button1”, “label1”, they should have descriptive names as will be discussed in class

Add 3 comboboxes for toppings choices or one Checked Listbox (it is up to you but the business rule is the customer can have up to 3 additional toppings) for this. Include 5 or so reasonable choices for the toppings to be shown. For each one the user selects $1.5 should be added to the subtotal when the order is calculated. Example: The user selects a medium pizza, no drink, and pulls down and selects “Pepperoni” and “Extra Cheese” and doesn’t select a third extra topping. Their subtotal should be $12. Make the Calculate button to be the ‘Accept’ button so the order is calculated if the user presses Enter. Make the Clear button the ‘Cancel’ button so the order is cleared when the user presses the Esc key.
