/* ANSWER:
what it does: start at 9 and count down to 1, displaying five divided
by the number for each step of the way.

float statement: to cast the 5/x as a float result, otherwise it would
be trying to do it as an integer calculation which would be a lot less
accurate (and which the %f specifier would not interpret correctly).

stop: the loop stops executing when x reaches 0, since it is reduced
by one before each loop.
