Small Bank System Project

Welcome to the Small Bank System Project! 🎉

This project simulates a basic bank system with functional programming principles. Although it shares similarities with a larger Bank Project, this version is much simpler and uses functional programming, unlike the Bank Project, which utilizes object-oriented programming (OOP).

Login System

Before accessing the system's main menu, you need to log in using your username and password.

• Validation:

  • The application checks if the entered username and password exist in the system.
  • If the credentials are valid, the main menu will be displayed.
  • If not, access is denied, and the user will be prompted to re-enter valid credentials.

• Permission-Based Access:

  • Users cannot access certain menus or perform specific actions unless they have the required permissions.
  • Each user’s access is restricted based on their assigned roles.
