Problem Description

In this assignment, you will be writing a C++ program for ATM machines to serve multiple customers. Each customer has a Personal Identification Number (PIN), and there are two types of customers. Type 1 customers have an odd PIN number and type 2 customers have an even PIN number. A type 2 customer will be charged $5 if the amount requested makes the balance fall below $500. A customer can process multiple withdrawals in a session. To end a session, the customer will enter a -1.

Input

At the beginning of the program, the customers balance is entered into the system.

Each customer will enter her/his PIN number and the amount they want to withdraw. The balance in the account must always be enough to cover the withdrawal plus any fees. If a fee is to be charged for a withdrawal amount, and there is not enough in the balance to cover the and the withdrawal amount, it should print, "Not enough money in your account to pay the fee!. See the Sample Runs for an example.

All PIN numbers are between 1000 and 9999, inclusive. If an entered PIN number is out of the range, then the program shall display a message and ask the customer to enter a PIN again until a valid PIN number is entered. Once a valid pin is entered, the program will run until the user enters a -1 to quit, or if the balance is zero.

The amount a customer may request is between $20 and $1000, inclusive. If an entered amount is out of the range, the program shall display a message and ask the customer to enter another amount again until a valid amount is entered. The withdrawal amount must be divisible by 5, as the smallest denomination that the ATM dispenses is a $5 bill. The balance in the account must be enough to cover the withdrawal.

If a type 2 customer enters a withdrawal amount that makes the balance fall below $500, the program shall display a message to warn the customer of the $5 fee. The balance in the account must be enough to cover the withdrawal and the fee. If there is not enough money in the balance, the withdrawal will not be processed.

In all cases, the withdrawal amount must not exceed the balance.

Output

After processing a valid request, the program shall display the amount requested, the fee if applicable, and the bills the customer is receiving. The ATM can deliver $20, $10, and $5 bills, and the machine will deliver the maximum possible number of $20 bills, one $10 bill if the remaining is at least 10, and one $5 bill if the remaining is at least 5. The customer enters a -1 to quit. The program shall display messages to assist customers to use the ATM. See the sample run later for details and formats of the output.

Pseudocode

Read in balance

Read in and validate PIN

Read in amount to be withdrawn, loop until -1

Validate withdrawl amount

If type 2 customer

Print Fee message

If not enough money with fee, print error

If there is enough money

Subtract withdrawl from amount

Subtract fee if type 2

Print withdrawl amount

Dispense money

Read in amount to be withdrawn

Notes

As a minimal output and to receive credit for doing program 2, your program MUST get the correct output for Test Case 1.

Each sentinel-controlled loop must be primed.

Follow the output format exactly.

Remember you cannot have magic numbers in your program.
