Hammad-Solutions/Bank-Management-System-Cpp-File-Handling — reverse-engineered prompt

Build me a simple beginner friendly bank management system in C++ that runs in the console and saves everything to a local file so the data is still there when I reopen it. I want it to feel like a small semester project, not something overly advanced.

The app should let a user create a new account, deposit money, withdraw money, check balance, transfer funds to another account, update account details, and delete an account. It should also keep a basic transaction history for each account if that fits the current project. Use clear menus and prompts so someone learning C++ can easily follow the flow.

Please keep it file based with no database, and make sure common mistakes are handled nicely, like invalid account numbers, low balance, or bad input. I’d like the code to be organized and readable for students, with comments where helpful. If anything is missing, look up current C++ file handling best practices online and finish it in a clean working way.
