🏦 BankQueue

BankQueue is a C++ command-line application that simulates a bank teller queue system.
It features separate interfaces for customers and tellers, along with queue management, transaction handling, and statistics tracking.

This project was developed as the final project for Data Structures and Algorithms, focusing on queue management, file handling, and modular program design.

✨ Features

• Dual Interface: Separate menus for customers and tellers
• Queue Management: Regular and VIP customer queues with priority handling
• Customer Transactions: Deposit, withdrawal, transfer, payments, account viewing
• Teller Operations: Serve customers, register new customers, view queue status
• Statistics Tracking: Total customers served, average service time, peak queue length
• Receipt Generation: Automatic transaction receipts with timestamps
• Data Persistence: Customer data stored in text files

🧠 What It Does

BankQueue simulates the workflow of a small bank teller system.

• Customers can register, join the queue, and perform transactions.
• Tellers can serve customers, monitor queues, and manage customer accounts.
• The system records statistics and generates receipts for each transaction.

This project demonstrates the use of queues, file handling, and modular program design in C++.

🧠 Concepts Demonstrated

• Queue data structures
• Priority queue handling
• File input/output
• Object-oriented programming
• Modular program design
• Command-line interfaces

📦 Requirements

• C++17 compatible compiler
• Linux, macOS, or Windows operating system

🏗️ Building

Linux/macOS

make

Windows (with CMake)

mkdir build && cd build
cmake ..

🚀 Future Improvements

• Store data using a database instead of text files
• Implement real-time queue updates
• Add transaction history search
