Please answer fast, I will like for sure.

The code is in C++

A bank charges a $ 10 monthly service fee, in addition to the following check usage fees: $.10 for each check, if you used less than 20 checks $.08 for each check, if you used between $ 2039 checks .06 for each check, if you used 40-59 checks $.04 for each check, if you used 60 or more checks The bank also charges $ 15 if the balance falls below $ 400 (before fees are deducted). Write a complete C ++ program that: 1) Ask the user what his opening balance is and how many checks he has written. 2) Compute and display the bank's service charges. You must validate that the number of checks entered by the user is not negative. If the balance entered by the user is negative, you should display a message saying that it has been overdrawn
