🏦 Bank Account Management System

A console-based bank account management application built in both C and C++, featuring file-based data storage for account persistence.

---

📋 Overview

This project is a terminal application that simulates basic banking operations. Account data is stored in a text file (Account.txt), making it persistent across sessions. The C++ version uses Object-Oriented Programming with a dedicated Account class, while the C version uses structs and procedural programming.

• Withdraw Cash — Withdraw money with password verification and insufficient funds check
• Check Balance — View current balance with account number and password verification
• File-Based Storage — Account data saved in Account.txt in the format AccountNo : Password : Balance
• Two Versions — C version uses structs; C++ version uses OOP with a class (getters/setters)
