Question

1. Ask for the number of hours used as a decimal fraction (a floating-point number). Validate the number and if it is invalid, keep asking the user for a valid number. If it is valid, round the number of hours up to the next integer value. Even though if it is a whole number, it can remain stored in a float.

While loop

user input

Enter you number of hours:

your usage charge is for (rounded) hours.
