🏦 Banking Management System (C++ | OOP)

A console-based Banking Management System developed in C++ using core Object-Oriented Programming (OOP) principles.

This project was built as part of my BS Software Engineering (2nd Semester – Object Oriented Programming) coursework.

---

📌 Overview

This system simulates basic banking operations for multiple clients and a manager.
It demonstrates clean class design, separation of declaration and implementation files, and structured menu-driven interaction.

The project focuses on applying foundational OOP concepts in a practical way.

🧱 Project Structure

Banking-Management-System
│
├── bank.h # Class declarations (Client & Manager)
├── bank.cpp # Class definitions
├── manager.cpp # Manager interface (main)
├── client1.cpp # Client 1 interface
├── client2.cpp # Client 2 interface
└── client3.cpp # Client 3 interface

👤 Client Functionalities

Each client can:

• 🔐 Login with username and password
• 📄 View account details
• 💰 Deposit money
• 🏧 Withdraw money (with re-authentication)
• 📊 Check account balance
• ✏️ Change name (after CNIC verification)

---

🧑‍💼 Manager Functionalities

The manager can:

• 🔐 Login securely (hidden password input using _getch())
• 📋 View all registered client account details

---

🛠 OOP Concepts Implemented

• Encapsulation (Private data members)
• Constructors (Default & Parameterized)
• Member Functions
• Header Guards
• Separate Compilation (.h and .cpp files)
• Object Composition (Manager contains Client objects)

⚙️ How to Compile & Run

Make sure you have g++ installed.

Compile Manager:

g++ manager.cpp bank.cpp -o manager
./manager

Compile Client 1:

g++ client1.cpp bank.cpp -o client1
./client1

(Same method for client2.cpp and client3.cpp.)

Limitations

• Console-based system (no GUI)
• No database or file handling (data is not persistent)
• Designed for academic learning purposes

Academic Context

Course: Object Oriented Programming
Program: BS Software Engineering
Semester: 2nd

Future Improvements

• File handling for data persistence
• Dynamic client creation
• Admin panel improvements
• Password encryption
• Input validation enhancements
