C++ Help! using multiple data type variable declarations, input with cin, output with cout including escape characters and formatting, arithmetic operations, boolean logic, while and do while loops, if-else, nested if-else-if and/or switch branching.

Here are some fun facts related to the project. The early 70's VW beetle came with a

1585cc air cooled motor that produced 50HP. The engine is highly customizable and can be downsized

for improved mileage or upsized for massive HP gains. Some engine components are bolt on. Some

components require that you take your components to the machine shop for work before you can bolt

them on. Either way, you will need to be mindful of the engine's compression ratio (cr). When the cr is

too low, you leave power and mileage on the table. If the cr is too high, your engine will be prone to

preignition, otherwise known as knock or ping. You will not be tested on the background.

Understanding of the background is not necessary for project completion.

Tasks:

You will need to compute several quantities.

1. The first is the engine volume (vol_engine):

(4*((bore/2)^2)*pi*stroke)/1000

2. The second is the combustion chamber volume (vol_chamber):

(((3/2)*((bore/2)^2)*pi)/1000)+head volume

3. The final quantity is the compression ratio (comp_ratio):

(engine volume/4/combustion chamber volume)+1

All pistons 88mm and larger require head machine work. All pistons 90.5mm and larger require case machine work. All strokes 78mm and larger require case machine work. All compression ratios 8.8 and higher are too high. All compression ratios 7.8 and lower are too low. The menus will accept menu pick q at any prompt as a way to terminate the program. Invalid menu picks simply redisplay the current menu

Consistency issues: In order to avoid total chaos in variable naming and typing, use the following:

Variable Name	Data type
vol_engine	Double
vol_chamber	Double
vol_head	Integer (from heads menu)
stroke	Integer (from crankshaft menu)
bore	Double (from pistons menu)
comp_ratio	Double
menu_pic	char (user input)
PI	double (3.14159)

Output:

Your output must conform strictly to the output format included with this document. You must use tabs

for alignment. Items in italics and underlined are user inputs. Items in smaller font are instructional and

are not to be output. Sample output follows.
