In the case of the python operators, I can find the code, but what about
the C code? are operators all together in one file, or scattered in
various modules?

I think some might, but as a rule they don't. It's often possible to
figure it out (i.e. if you need an active object, or mode, or the right
space), but sometimes not (for instance, in what context should quit()
refuse to quit?)
