Question

After reviewing this chapter, you feel much more comfortable with classes but you now need create your own class objects. One “thing” which seems to be prevalent in all of the applications run from the moose skateboards web site is a Skateboard.

You have decided to consolidate all of the data and modules involved with skateboards and build a class file to be used with other applications. For this case study you’ll need a design class file itself along with the driver (application logic) class to test the code within the class.

.Create the pseudo-code that will hold the following data elements along with accessor in mutator methods.

.skateboard model number

.skateboard color

.skateboard serial number

.skateboard cost

.skateboard price

.After the class called Skateboard create an app to print the serial number and model number a sales summary showing the price, cost and the calculated profit (Price - Cost).
