The Speed of Sound
The speed of sound varies depending on the medium through which it travels. In general,
sound travels fastest in rigid media, such as steel, slower in liquid media, such as water, and
slowest of all in gases, such as air. The following table shows the approximate speed of
sound, measured in feet per second, in air, water, and steel.
Write a program that displays a menu allowing the user to select air water, or steel. After
the user has made a selection, the number of feet a sound wave will travel in the selected
medium should be entered. The program will then display the amount of time it will take.
(Round the answer to four decimal places.)
Input Validation: Decide how the program should handle an illegal input for the
menu choice or a negative value for the distance.
