Homework SourseI finished most of the program but having trouble with some
I finished most of the program, but having trouble with some key features. I bolded and italicized the parts I can\'t figure out. I included my code at the bottom. Thanks!
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 characters)
Normally accessible from a standard US keyboard
If login was not successful (for example the id or password did not match) then the user must be returned to the introduction menu.
Items in BOLD are user input:
