1. Library Fines

A local public library needs a program to calculate the overdue fines owed by its patrons. The library needs the clerk to enter the full name and age of the patron. The clerk also needs to enter the name and the number of days overdue for the item. (The library accounts for full days overdue and not partial days overdue.) The library wants the clerk to be presented with a menu from which the type of material overdue can be chosen. The menu should look as follows:

1. Book
2. Magazine
3. DVD

Books that are overdue are assessed a fine of 50 cents per day. Magazines are assessed a fine of 25 cents per day. DVDs are assessed a fine of $1.50 a day. There is a maximum fine assessed of $5.00. Senior Citizens (over the age of 70) do not pay fines. Juvenile patrons (ages 6 through 17) pay a maximum fine of $1.00.

Once the fine has been calculated all information about the patron and the overdue material should be printed to the screen. Here is an example of the report that should be output:

Name Mickey Mouse
Age 22
Item Name Fantasia
Item Type DVD
Number of Days Overdue 2
Overdue Fine $3.00

Each time the program is executed it calculates the fine for a single item. If the user enters invalid data, then a message must be presented on the screen specifying the invalid information and the calculation is aborted.

Also remember we do not know how to compare strings.

a) Rewrite this problem statement in your own words. Create a list of short bulleted phrases showing all details about this problem. This list should include both the explicitly defined and implied details in the problem statement. Consider what information the program needs to remember in order to meet the requirements of the problem statement. Consider what tasks need to be completed by the program in order to meet the requirements of the problem statement. (Hint - do you think this rewritten problem statement will be longer or shorter than the original problem statement?)

Print out this rewritten problem statement to turn in with this homework.

b) Run your program multiple times using the following information as input. After each run of the program save your entire console output screen to a text file as discussed in our labs.
