In C++ please. I am trying to understand conditionals. I have some code but im stuck.

An international phone call is billed by the minute according to this scheme: Calls up to 10 minutes cost a flat $5. Calls over 10 minutes but less than 30 cost $.50 per minute. Calls 30 minutes or longer cost a base of $15.00 plus $.30 per minute over 30. Write a program to read in the duration of a call as an integer and output the total cost as a decimal. Do not worry about making it look like money.
