Question

Please help:

a.I need to draw the hierarchy chart and then plan the logic for a program needed by Hometown Bank. The program determines a monthly checking account fee. Input includes an account balance and the number of times the account was overdrawn. The output is the fee, which is 1 percent of the balance minus 5 dollars for each time the account was overdrawn. Use three modules. The main program declares global variables and calls housekeeping, detail, and end-of-job modules. The housekeeping module prompts for and accepts a balances. The detail module prompts for and accepts the number of overdrafts, computes the fee, and displays the result. The end-of-job module displays the message Thanks for using this program.

b. I need to revise the banking program so that it runs continuously for any number of accounts. The detail loop executes continuously while the balance entered is not negative; in addition to calculating the fee, it prompts the user for and gets the balance for the next account. The end-of-job module executes after a number less than 0 is entered for the account balance.
