# 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.
