basic C++ bank project

I need help writing this program: I have my own version I wrote but would like to see how someone else can approach it. this is for a basic console application that doesn't need to store data anywhere. So when I run it from visual studio it runs as if it doesn't have any data stored onto it already. Functional Requirements: Save-More is a small community bank that offers its customers 3 types of Bank Accounts – an interest bearing savings account, a checking account and a certificate of deposit. All Bank accounts have an Account Number, an Interest rate and a Balance – and have the ability to withdraw funds, deposit funds and display the account’s attributes. The Savings account has a variable interest rate. Balances under $10,000 earn 1% APR interest and balances >= $10,000 earn 2% APR. The rate is updated dynamically if and when the balance changes. Interest is compounded monthly and added to the balance. All savings withdrawals are charged a fee of $2, deducted from the balance at the time of withdrawal. The Checking Account is non-interest bearing. If the checking account balance drops below $500 a fee of $5.00 is deducted from the balance. Checking accounts have the capability to order checks for $15, deducted directly from the balance. The Certificate of Deposit (CD) earns 10% with a 5 year term and 5% for anything less. The term is set on account creation and cannot be updated. Interest is compounded monthly and added to the balance. If funds are withdrawn before the term is over, a 10% fee on the entire pre-withdrawal balance is levied Regardless of the type of account, customers are never allowed to go negative with a withdrawal. Program Requirements: Design and implement a set of classes in C++ to support all of the above functional requirements. Define class member data, constructors and member functions as required to fulfill on the requirements. The class structures defined should demonstrate inheritance implementing Savings, Checking and CD accounts as derived classes of the base class Bank Account. Deposit and withdrawal methods should return a value to indicate success or failure of the method (0=success -1=failure) If an operation will make an account go negative, the operation should not be completed and a failure returned from the method The classes created should be exercised/tested by leveraging your main() function and performing the following operations (in order) Create a new savings account and deposit $10k Create a new checking account and deposit $600 Create a new CD account with a 3 year term and deposit $10K Get and display the attributes for each account Calculate monthly interest for the savings account Calculate the monthly interest for the CD account Get and display the attributes for each account Order checks Withdraw $200 from checking Withdraw $1000 from Savings Perform an early withdrawal of $2000 from the CD account Get and display the account attributes for each account Polymorphism must be demonstrated with the creation of the bank accounts
