Assignment: Credit Card Company Program Cont’d

• Text Output (Part A of your homework):

• Create a new account: Print “Account created” on success or “Creation Failed” on

failure (duplicate credit card number)

• Pay balance: Print “Fully paid off” on full payment or “partially paid off” if partial

payment is made.

• Make a purchase: Print “Purchase made” on success or “Purchase Failed” on

failure (purchase amount exceeds the remaining credit limit)

• Check balance: Print “No balance to pay” if balance is 0, “Card maxed out” if

balance = credit limit (credit limit is reached), “Your balance is XXX” otherwise.

• Edit an account: Print “Account modified” on success or “Modification Failed” on

failure (duplicate credit card number)

• Close an account: Print “Account closed” on success or “Closing Failed” on failure

(cannot close an account if balance is not paid off first)
