Bank Management System (C Project)

This project is a console-based Bank Management System developed entirely in the C programming language By Yuvraj Kumar Singh. It is designed to simulate the fundamental operations of a bank, focusing on secure user interaction and robust data persistence using local file storage.

The system allows multiple users to create accounts, log in, and perform core banking functions such as deposits, withdrawals, and reviewing their transaction history. A separate, secure Admin Panel is included for managing the user base, setting system-wide limits, and handling direct account transfers.
