This what I\'m suppose to do and this is what I have so far.

In this assignment you are to create an interactive line command driven C++ program that allows a user to do the following:

Create a bank account by supplying a user id and password

Login using this id and password

Quit the program

Upon successful login, the user will be presented with a menu to do one or more of the following actions:

Withdraw money

Deposit money

Request balance

Quit the program

Ensure that you remove any unnecessary punctuation from monetary input (for example, all $ or other currency symbols should be removed prior to processing, do NOT display an error message to the user for characters which can be removed from the input string without changing the intended value).

Format all monetary outputs on the display Currency (e.g. $ 25,928.43) with all decimal places containing digits.

The User ID and password fields may be any combination of characters which are:

Visible when displayed on the screen (no control characters0
