Banking System in C++

This C++ project simulates basic banking operations using object-oriented programming principles. It provides functionalities to manage bank accounts, perform transactions, and persist data using file handling.

Features

• Account Management: Create savings or checking accounts with initial balances.
• Transaction Handling: Deposit funds, withdraw money, and transfer money between accounts.
• Data Persistence: Accounts are stored and retrieved from a text file (accounts.txt).
• Error Handling: Manage errors such as insufficient balance or non-existent accounts gracefully.
• User Interface: Interactive console-based interface for user interaction.
• 

Classes and Components

Account Class Hierarchy

• Account: Base class for generic bank account operations.
• SavingsAccount: Derived class with specific rules for savings accounts.
• CheckingAccount: Derived class with specific rules for checking accounts.

Bank Class

• Manages accounts using a map<int, Account*>.
• Provides methods to add, delete, retrieve, and display accounts.
• Handles transactions such as deposit, withdrawal, and transfer.

Transaction Classes

• Transaction: Abstract base class defining common transaction methods.
• DepositTransaction: Implements deposit operation.
• WithdrawTransaction: Implements withdrawal operation.
• Transfer: Implements fund transfer between accounts.

File Handling

• Accounts are serialized (save_to_file()) and deserialized (load_from_file()) to maintain data persistence across sessions.

Usage

1. Clone the Repository:

   git clone https://github.com/your-username/banking-system.git
   cd banking-system

2. Compile and Run:

   • Compile the main.cpp file using your C++ compiler:

     g++ main.cpp -o banking_system

   • Run the executable:

     ./banking_system

3. Interact with the Banking System:

   • Follow the console prompts to create accounts, perform transactions, and manage accounts.

4. Data Persistence:

   • Ensure accounts.txt is present in the same directory for saving and loading account data.
