Ok, how do you make a program where there is 14 cars with 4 different combinations such as colour, style, brand, transmission.

I am suppose to make a program that where you input the 4 peices of information (colour, style, brand, transmission) and it figures out the cost for you.

For example,

Brand Transmission Colour Style Cost
BMW Automatic Blue Two Door $34695
Volvo Manual Green Four Door $28983

Except there are 14 different combinations not just 2. There are 4 cars, 4 colours, 2 style, 2 transmission.

Thanks for the help!

what you are attempting to do is called hardcoding, by which i mean writing an if for every possibility, a much more efficient way of doing this is with an array

If you have 4 cars, 4 colours, 2 styles, and 2 transmissions, then you have 4*4*2*2 different combinations, which is 64 unique cars.
To make an 'if' for every car would suck, so give a price to each choice, then add the cost of the 4 choices together to get the final price.

BMW=$25000
Automatic=$3000
Blue=$2695
Two Door=$4000

BMW+Automatic+Blue+Two Door=$34695

what you can do is store the price in a 4d array (or a 1d array with a mapping function from 4 values), then you have an if statement for color, style, brand, and transmittion and give a numeric value to those, then you just look up the cost in your array according to those values.

like Daniel has suggested, mapping the 4 values into a single array would be very efficient. You could store the color, brand , etc.. like so :
color * 1 + brand * 2 + transmission * 4 + car * 8

(Since I didn't read your complete question, this might not be helpful AT ALL....I apologize if that's the case Sad)

EDIT : changed a few words

Two Door=$4000

BMW+Automatic+Blue+Two Door=$34695


this would by far be the easiest thing to do, just write variables for each component (car, transmission, colour, style) then just say
if BMW=$395 and blue=$4
then BMW+blue=total cost

or skip that if entirely,

totalCost := brand + transmission + color + style
