General Description: For this assignment you will be writing a point of sale program which allows a user to build a computer and calculate the total cost of the build. You will create a menu-driven program which will give the user several options for building the computer. This program will have you juggling several different classes at once. NOTE 1: You may NOT make any changes to the classes as they are defined here. You may not add to, or take from the class. They need to be designed following the UML diagrams exactly. You MAY however add any additional classes you feel will enhance your program or make the code more organized NOTE 2: The computer parts and prices are outdated by this point. If you wish to do your own research and use newer parts and costs feel free! You must have at least three of each type of computer part. Feel free to add more parts as you see fit.
