This isn't a homework project, is it?

Have you done anything on the code yet? If so, please post what you've done so far.

We don't do your homework here for you. If you don't show effort on your part, this post might get closed/deleted.

yes, this is my C++ assignment.
i know this assignment want to using the Object-Oriented concepts(inheritance, polymorphism etc).
i know to defind some classes like create account, and what type of acount custermer want to create, but i dont know how to search back the account custemer created.

Like I said, if this is an assignment, work on it some yourself, and if you get stuck, post the code you've written so far, and ask if we can help troubleshoot your already written code.

We don't do your homework for you-- we help you figure out your problems. Many of us here (not including me, though) are excellent programmers, but we're not willing to help unless you're willing to help yourself first.

ok, i just recieve this project in one week later, i will try to write somthing if i have stuck, i will post the code.
