## Overview

This educational C++ console bank system evolves from client CRUD into a final version with transactions, login, user administration, and permission checks. The main workflow is console input → login → main menu → permission-checked action, with client balances and user records persisted in text files. The sampled code is a partial excerpt of the final, single-file implementation; menu-to-action and authentication relationships also follow the README’s documented flow, so uncertain internal call wiring is omitted.
