Conference Registration System

Create an application that calculates the registration fees for a conference. The general conference

registration fee is $$895$ per person, and student registration is $$495$ per person. There is also an optional

opening night dinner with a keynote speech for $$30$ per person. In addition, the optional preconference

workshops listed in Table $13-10$ are available.

Table $13-10$

Optional preconference workshops

The application should allow the user to select the registration type, the optional opening night dinner and

keynote speech, and as many preconference workshops as desired. The total cost should be displayed. 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.
