Revise the program shown in Segment 596 such that it accepts an
additional flag, v, for verbose. If v is provided
as a flag, the program is to perform as it does now. Otherwise, it is to
suppress the full-sentence output and return numbers only: It returns a
floating-point price if the p flag is provided, an integer number of
shares if the n flag is provided, both numbers if both flags are
provided, and nothing if neither flag is provided.
