ATM Project (C++)

Overview

This project is a simple ATM simulation system implemented in C++. It was developed for educational purposes to practice Object-Oriented Programming (OOP) concepts such as inheritance, polymorphism, encapsulation, and abstraction.

The project models different types of bank accounts and provides common ATM operations like deposit, withdrawal, and monthly updates.

---

Features

• Create different account types:

  • Savings Account (with interest rate).
  • Checking Account (with overdraft limit).

• Deposit and withdraw funds.

• Apply monthly updates:

  • Interest added to savings accounts.
  • Service fees applied to checking accounts.

• Print account statements.

Learning Objectives

This project was built to strengthen understanding of:

• Abstract classes and pure virtual functions.
• Method overriding (polymorphism in action).
• Encapsulation of account details.
• Working with dynamic memory and destructors.
• Managing multiple objects using STL containers (std::vector).

---

Notes

• The project is designed for educational purposes only.

• Code is kept simple and easy to read, focusing on clarity over complexity.

• Future extensions may include:

  • Transaction history.
  • User authentication.
  • Graphical or menu-based interface.
