Using constructs from this chapter or earlier,$$complete Programming Challenges #$2,$ Skateboard Designer, on page $907.$

Note: Use only combo boxes for the four lists. In addition, have a "clear" button that resets the total back to $0.$ Also have a "print receipt" button that simply does the same thing as the clear button.

Each class should be in a separate file $($except for events and event listeners$).$ Table $13-9$

Skateboard products

In addition, the Skate Shop sells the following miscellaneous products:

$-$ Grip tape: $\backslash (\backslash$$ $10\backslash )$

$-$ Bearings: $\backslash$$$30$

$-$ Riser pads: $\backslash$$$2$

$-$ Nuts $\backslash$& bolts kit: $\backslash$$$3$

Create an application that allows the user to select one deck, one truck assembly, and one wheel set from either Listview controls or ComboBox controls. The application should also have a Listview that allows the user to select multiple miscellaneous products. The application should display the subtotal, the amount of sales tax $($at $7$ percent$),$ and the total of the order. Avoid poor programming practices in your assignments. Many web sites contain programs that are poorly written. The text contains many examples of programs that use good programming practices. Use the text as a guide.

Here is a list of things for which I will deduct points. We will learn about these as the semester progresses.

$-$ You should have comments in your program to explain what your program is doing. They should be meaningful comments. I will deduct points if you don't have comments.

$-$ You should have only one exit point from your program and any methods. $($Do not have multiple return statements$).$ I may deduct points if you have multiple exit points.

$-$ Do not use the word "invalid" in any user message as it has multiple meanings. I will deduct points if you use "invalid".

$-$ You should use appropriate and meaningful variable names. I will deduct points if you use single letter variable names or names that don't reflect the usage of the variable.

$-$ Do not use break, continue, or intentional infinite loops $($while true$)$ in your program to alter the program flow. Fix your logic. I will deduct points if you do$.$

$-$ You should use appropriate user prompts. They should be simple, accurate, have good grammar, and not have any misspellings. I may deduct points if you have confusing prompts.

$-$ You should properly label and format output or results. It should be obvious what your results mean. I will deduct points if your output or results are confusing or not formatted as they should be $($for example, currency should either have $0$ or $2$ decimal places$).$

$-$ Each assignment starts with the words "using constructs from this chapter or earlier." You can only use concepts from the chapter the assignment is from, or previous chapters. I will deduct points if you use things we haven't covered or are not in the text.
