## Overview

This is a console banking system: a user enters the application menu, selects client, transaction, user, log, or currency functions, and the corresponding screens operate on domain objects backed by text files. The documented product also includes login, permission checks, transfer and login auditing, and currency conversion. Sampled code confirms menu dispatch, client persistence and transfers, user persistence and audit records, and currency-rate operations; links for unsampled screen internals are omitted where their wiring cannot be verified.

Main entry points: [`Bank OOP Project/clsMainScreen.h`](https://github.com/moazabdulsalam/oop-bank-project/blob/main/Bank%20OOP%20Project/clsMainScreen.h) (Main menu), [`Bank OOP Project/clsBankClient.h`](https://github.com/moazabdulsalam/oop-bank-project/blob/main/Bank%20OOP%20Project/clsBankClient.h) (Bank client model), [`Bank OOP Project/clsUser.h`](https://github.com/moazabdulsalam/oop-bank-project/blob/main/Bank%20OOP%20Project/clsUser.h) (User model), [`Bank OOP Project/clsTransactionsScreen.h`](https://github.com/moazabdulsalam/oop-bank-project/blob/main/Bank%20OOP%20Project/clsTransactionsScreen.h) (Transaction menu)
