Chapter 4, Problem 14PP

Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a program that can take a start time and an end time and calculate the difference in minutes between them. The end time will always be within 24 hours of the start time. Use military notation for both the start and end times (e.g., 0000 for midnight and 2359 for one minute before midnight).

Write a function that takes as input a start time and an end time represented as an int, using military notation. The function should return the difference in minutes as an integer. Write a driver program that calls your subroutine with times entered by the user.

Hint: Be careful of time intervals that start before midnight and end the following day.
