imp_metric should print two tables side by side
(equivalent to a 4-column) table, one for the conversion from
yards into meters, the other one for the conversion from km into
miles. The output should use int values, but you can use
the floating point conversion factors of 0.9144 (from
yards to meters) and 1.609344 (from mile to km). Try to
make the program round correctly!
