Yeah, I think this should be something that is learned from the cylinder
data structure directly. Think about it. One of the cylinders is likely O₂
or something similar, one is air or some trimix gas. It's pretty obvious
which one is your oxygen cylinder, which one is your dillutant, right?

So please, do not hard code it. Create two helper functions that figure
out which one is which and then use two variables with appropriate names
to hold the result.
