Long-Distance Calls
A long-distance carrier charges the following rates for telephone calls:
Starting Time of Call | Rate per Minute |
00:00–06:59 | 0.05 |
07:00–19:00 | 0.45 |
19:01–23:59 | 0.20 |
Write a program that asks for the starting time and the number of minutes of the call, and displays the charges. The program should ask for the time to be entered as a floatingpoint number in the form HH.MM. For example, 07:00 hours will be entered as 07.00, and 16:28 hours will be entered as 16.28.
Input Validation: The program should not accept times that are greater than 23:59. Also, no number whose last two digits are greater than 59 should be accepted. Hint: Assuming num is a floating-point variable, the following expression will give you its fractional part:
num − static_cast
