Question

Given the following requirement:

An online computer hardware shop wants to allow its users to build their desired computers.

Users of the application can pick several hardware parts and build their computers from

scratch and get an estimated price. Computers should be composed of a motherboard, a

RAM, a CPU, one or more GPUs, one or more storage units (HDDs, SSDs), a PSU, and

multiple peripherals for the interaction with the computer (mouse, keyboard, screen, etc.).

All of these components should have a price. You can assign random sensible prices to each

piece of hardware. Make sure that there are at least 3 options for each concrete instance of

hardware.

You are free to make assumptions for the details that are not mentioned in the above

requirement.

a) Design a software for the above requirement and draw the UML class diagram for the

designed software. You must use the Builder Pattern. Otherwise, you cannot get any

point from this section. (20 points)

b) Implement the previously designed software (the exact one that you draw the UML for)

with either C++ or Java. If you pick the C++ option, make sure your program does not

leak memory. If any memory leak is detected, it will cost you some grades. You can use

Valgrind software to analyze your program. (30 points)
