Write a program that displays a menu allowing the user to select air, water, or steel, and then has the user enter the number of feet a sound wave will travel in the selected medium. The program should then compute and display (with four decimal places) the number of seconds it will take. Your program should check if the user enters a valid menu choice, if not, it should terminate with an appropriate message.
Design: First use an IPO chart to design your program, showing inputs, outputs, and process written in pseudocode and use your chart to write your program.
