C++

A long distance carrier charges the following rates for telephone calls:

Starting Time Of Call	Rate per Minute
0:00-06:59	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 floating-point number in the form HH.MM. For example, 7:00 hours will be entered as 7.00, 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 be accepeted. Hint: Assuming num is a floating point variable, the following expression will give you it fractional part:

num - static_cast(num)
