Question

Bank charges $10 per month plus the following check fees for a commercial checking account:

 $.10 each for fewer than 20 checks

$.08 each for 20–39 checks

$.06 each for 40–59 checks

$.04 each for 60 or more checks

The bank also charges an extra $15 if the balance of the account falls below $400 (before any check fees are applied).

 Write a program that asks for the beginning balance and the number of checks written.

Compute and display the bank’s service fees for the month (30 days).

Input Validation: Do not accept a negative value for the number of checks written. If a negative value is given for the beginning balance, display an urgent message indicating the account is overdrawn.
