AmrTamerTech/clsBank_System-Cpp — reverse-engineered prompt

Build me a simple C++ console bank management system like a small back office tool for a bank employee. It should let users log in, then show menus for managing clients, handling transactions, managing other users, and doing currency exchange.

I want client records to be saved in text files so the data stays after closing the program. Users should be able to add, update, delete, search, and list clients. The transaction area should support deposits, withdrawals, total balances, and logs. Add user accounts with permissions so some users can be blocked from features they’re not allowed to use.

Please include a basic encryption method for saved user or client data, login and logout screens, failed login handling, and activity tracking. Also add a currency exchange menu where I can list currencies, search for one, update rates, and calculate conversions.

Keep it object oriented, modular, and easy to run from the command line. Look up current C++ docs if needed.
