Answer to Question #282811 in C++ for levi

Question

AUTOMATED TELLER MACHINE

Create a C++ program that will

• Deposit cash amount in a bank account
• Check available balance of the account
• Withdraw cash amount from an account
• Compute for the interest earned for balances greater than Php 10,000.00
• Charges for having a balance below the required minimum

Maintaining balance is Php 5,000.00

Interest rate is 5%

Bank charge is 2%

PIN (Personal Identification Number) is required to do a bank transaction

The program gives the user an option to change PIN
