Write a menu-driven program to change a time in seconds to other units (minutes, hours, etc.). The main script will loop to continue until the user chooses to exit. Every time in the loop, the script will form a random time in seconds, call a function to present a menu of options, and print the converted time. The conversions must be made by individual functions (e.g. one to convert from seconds to minutes). Every user-entries must be error-checked.
