Validate Account Module Shall check to see that the account number that the user entered is valid and that the pin number the user entered is correct for the given account number. The inputs it shall receive are the account number and the pin that the user entered. The module shall then access the master Banking Accounts file and search for the account number that was entered. If the account number is found it shall then check to see if the pin number the user entered is correct for that account number. If either the account number or pin is invalid the program shall display a message to the user stating that the account number or pin is invalid. It shall not specify which of the two was invalid for security reasons. This module does not call any other modules but instead will be called from the login/logout module. Banking Module Shall deal with all banking transactions which are deposit, withdrawal and balance lookup.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
