Bank Management System

Description

This is a simple console-based Bank Management System written in C++. It allows users to manage accounts, including creating new accounts, depositing and withdrawing money, modifying accounts, and deleting them. The data is stored in a binary file and operations are performed using file handling techniques.

Features

• Create a New Account: Allows the user to create a new account by providing details such as account number, account holder's name, account type (C/S), and initial deposit.
• Deposit Amount: Deposits an amount to an existing account.
• Withdraw Amount: Withdraws an amount from an existing account, ensuring that the balance doesn't go negative.
• Balance Enquiry: Displays the details of a particular account based on the account number.
• Display All Accounts: Displays a list of all account holders with their account details.
• Close an Account: Deletes an account by removing it from the file.
• Modify Account: Allows the user to update the details of an existing account.

How It Works

The program uses C++ classes to manage the account details and file handling to store account information in a binary file (account.dat). Here's a brief explanation of how each feature works:

• When an account is created, it's written to the binary file.
• For deposit, withdrawal, and modifications, the program reads from the file, modifies the data in memory, and then writes the updated data back to the file.
• Each account is stored with an account number, name, account type (C for Current, S for Savings), and balance.
