Long-Distance Calls

A long-distance carrier charges the following rates for telephone calls between the United

States and Mexico:

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, 07:00 hours should be entered as 07.00, and

16:28 hours should be entered as 16.28.

Hint: To find the fractional part of the entered number you can use the following

expression:

startTime - static_cast(startTime)

Input Validation: Figure out what inputs are valid for startTime, and how the

program will handle invalid inputs.
