## Overview

The tree describes a console banking application with client and user administration, banking transactions, currency tools, and login/access control. The sampled OOP client screens call clsBankClient for client lookup and persistence; its client records and transfer log use local text files. The tree also contains main.cpp, whose sampled code shows a separate, simpler client-management and transaction menu using clints.txt. No README is present, and most OOP modules were not sampled, so their connections are limited to what their names and the sampled client code support.

Main entry points: [`clsBankClient.cpp`](https://github.com/yuseefahmdali-jpg/bank_project/blob/main/clsBankClient.cpp) (Client model), [`main.cpp`](https://github.com/yuseefahmdali-jpg/bank_project/blob/main/main.cpp) (Legacy menu), [`clsLoginScreen.cpp`](https://github.com/yuseefahmdali-jpg/bank_project/blob/main/clsLoginScreen.cpp) (Login screen), [`clsManageUsersScreen.cpp`](https://github.com/yuseefahmdali-jpg/bank_project/blob/main/clsManageUsersScreen.cpp) (User administration)
