🏦 Natnael International Bank — Management System

A console-based Bank Management System written in C++, built as a personal learning project to practice core programming concepts including structs, file I/O, functions, and modular design. The system simulates real banking operations and persists all data using binary file storage.

---

📌 Project Overview

This program runs entirely in the terminal/command prompt and allows users to create and manage bank accounts, perform financial transactions, and view account records — all without needing a database or internet connection. Data is saved to a local binary file (filename.bin) so records survive between program runs.

✨ Features

• Create Account — Register a new bank account with a name, account number, and opening balance
• Deposit — Add funds to any existing account
• Withdraw — Remove funds with overdraft protection (cannot withdraw more than the balance)
• Transfer — Send money between two accounts with full validation
• View Account — Look up a specific account by account number
• Modify Account — Update account holder details
• Delete Account — Permanently remove an account from the system
• List All Accounts — Display a neatly formatted table of all registered accounts
• Persistent Storage — All data is saved to filename.bin automatically on every change
• Input Validation — All numeric inputs are validated; invalid entries prompt the user to re-enter

▶️ Windows (Command Prompt / PowerShell)

g++ project.cpp -o project.exe
project.exe

---

▶️ Linux

g++ project.cpp -o project
./project

---

▶️ macOS

g++ project.cpp -o project
./project

⚠️ On macOS, if g++ is not found, install Xcode Command Line Tools:

xcode-select --install

Note: filename.bin (the data file) is intentionally excluded from this repository via .gitignore. It will be created automatically the first time you run the program.

🔮 Future Features

These are planned improvements for future versions of this project:

• Login system — Password-protect accounts with encrypted PIN storage
• Transaction history — Log and display a full history of deposits, withdrawals, and transfers per account
• Interest calculator — Automatically apply monthly interest to savings accounts
• Admin vs User roles — Separate access levels for bank staff and customers
• Search by name — Look up accounts by account holder name, not just account number
• GUI interface — Migrate from console to a graphical UI using a framework like Qt
• CSV/text export — Export account summaries to a readable .csv or .txt file
• Multiple account types — Support for savings, checking, and loan accounts
