Simple Bank System (C++ / OOP) 🏦💻

A console-based Bank Management System built with C++ using Object-Oriented Programming (OOP) and a simple “screens” architecture (menu screens, transaction screens, user management screens, etc.). ✅

This project is designed as a learning-focused system that demonstrates:

• Clean separation between models (Client/User/Currency)
• UI screens (menus & workflows)
• File-based persistence (TXT files)

Full project explanation, details, and walkthrough are organized inside the repository files.

Project Structure 🧩

The repository is organized around:

• Core entities (models): client, user, currency
• Screens: each feature is presented through a dedicated “screen” class
• Data files: stored as .txt files for simplicity

Common important files:

• BankSystem.cpp (entry point)
• clsBankClient.h, clsUser.h, clsCurrency.h (core models)
• clsMainScreen.h + multiple screen headers (feature UI)
• Clients.txt, Users.txt, Currencies.txt, TransfersLog.txt, LoginRegister.txt (data/log files)

---

Data Storage 📁

This system uses plain text files for storage/logging:

• Clients.txt → client records
• Users.txt → system users
• Currencies.txt → currency rates/info
• TransfersLog.txt → transfer history
• LoginRegister.txt → login activity log

How to Run ▶️

Option A — Visual Studio (recommended on Windows) 🪟

1. Open the .vcxproj project file in Visual Studio.
2. Build in Debug or Release.
3. Run the project.

Option B — Any C++ compiler ⚙️

If you prefer CLI compilers (g++/clang++), compile the project entry + required headers in your environment.

Note: This repo is structured as a Visual Studio project, so Option A is the easiest.

Future Improvements 🚀

• Replace TXT persistence with a database (SQLite, PostgreSQL, etc.)
• Add input validation + better error messages
• Add role-based permissions (Admin/Employee)
• Export logs to CSV/JSON
