CS12 Array Processing - 20 points

This project is designed to give students practice with array declaration, loading, and processing. Customer information (id, name, discount code) stored in a data file should be loaded into three parallel arrays. The discount code should then be looked up in a discount code array to get the discount rate. The appropriate discount rate should then be loaded into the 4th parallel array. The values in the four parallel arrays should be displayed in list boxes so that manipulation of the data can be displayed. Two constant arrays to store the discount codes and discount rates will be needed.

The four parallel arrays should be able to hold up to 10 customers. The program should allow the user to load the arrays once, sort by id, sort by name, and search by name. The name to search for will be entered in a textbox. If there is a match in the list, the name should be selected in the list box. If the name is not found, a message should be displayed in a label. The early exit logic should be included in the search routine (see lecture notes and cs12ex).

Sample Form:

Sample Form (cs12_interface.jpg)

Additional Notes:

To speed up development, the interface for the project is provided as a self-extracting CS12 archive that should be downloaded and expanded.

The headers for the various required methods are provided along with the interface code.
Consider coding the program incrementally.
1st: code load, assign, and display methods
2nd: code sort by id and swap values methods
3rd: code sort by name and search by name

In displayArrays use ToString("N2") to display the rate with two digits after the decimal point.

Data for the constant arrays, Discount Code and Discount Rate are as follows:

        Discount
     Code     Rate
       A      0.03    Administrators
       F      0.05    Faculty
       S      0.10    Student
       X      0.00    No Discount

The data file CS12.txt is included in the archive and it contains the data shown below.
Each data item is stored on separate lines so use ReadLine.
