I need help writing a C Form Program that will use 3 Parallel Arrays to store Data. I have the form set up - and the clear button working. But I am lost as to how do the rest...
My requirements are below:
Create a form called Eddie's Equipment Rental w/ a list box, a Duration text box, a Charge text box a display button and a clear button.
It should look like this:


1. Eddie charges one amount for a full day rental and another amount for half day rentals - use 3 parallel arrays to store the data
Data is as follows:
Equipment Rug Cleaner - Lawn Mower - Paint Sprayer
HalfDay Charge 16 12 20
Full Day Charge 24 18 30

2. Load the list box during the form load event
3. User should click on the ime in the listbox to seelct the equipment
4. The user must enter F or H for full or half Day - add an error check
5. The Display Charge button will display the appropriat amount in the Rental Charge text box
6. The clear Button will Clear the 2 text boxes
I have the form... and the clear button working. Code is below:
