📢 Introduction
Are you a beginner in C programming looking for a real-world project? This ATM
Machine in C is a great academic project for school students (8-16 years old) to learn file handling, authentication, and modular programming in C.
In
this post, we will cover:
✅ How the ATM system works
✅ Key features and functionalities
✅ Complete C Code for the ATM system
✅ How to set up and run it in Code::Blocks IDE
💻 What is an ATM
Machine in C?
This ATM
Machine project is a simple
console-based system
that simulates basic banking operations like:
✔ User Authentication (Login via Account Number & PIN)
✔ Balance Inquiry
✔ Cash Withdrawal
(with insufficient balance check)
✔ Cash Deposit
✔ Fund Transfer
(from one account to another)
✔ Transaction Logging (Stored in a
file for future reference)
It uses file handling to store account details and transaction history,
making it a realistic yet simple project.
🛠️ System
Requirements
●
Programming Language: C
●
IDE: Code::Blocks with MinGW Compiler
●
Platform: Windows 10
●
Database: Text files (accounts.txt, transactions.txt)
📜 How Does the ATM
Machine Work?
1️⃣ Login: The user enters their Account Number & PIN for authentication.
2️⃣ Select Operation: Choose from Balance Inquiry, Withdrawal, Deposit, Fund
Transfer or Exit.
3️⃣ Process Transaction: Based on
the selection, the system updates the balance
and transaction history in files.
4️⃣ Logout: After transactions, the
user logs out, and changes are saved permanently.
