Problem I 30 points

A car manufacturing follows certain steps to build a car. Here is the process: build car frame, add engine, driving wheels, dashboard and energy source. There are three different cars named standard, sport and electronic.

Parts	Standard Car	Sport Car	Electronic Car
Frame	Standard	Aerodynamic	X-frame
Engine	Inline	V-Engine	Brushless
Driving wheels	FWD	AWD	RWD
Dashboard	Standard	Premium	Digital
Energy	Standard	Enhanced	Battery

Note that a buyer can choose different car, but the construction process is the same. Use builder pattern to construct the car by building each part and putting them all together. The main program asks buyer to choose a car, then display the car information on the screen. For example, if the buyer chooses Standard car, the result should show on screen as following

Standard car:

Frame: Standard

Engine: Inline

Driving: FWD

Dashboard: Standard

Energy: Standard
