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.

Setup and Compilation

Requirements

  • A C++ compiler (like GCC or any IDE that supports C++ programming).

Compilation Steps

  1. Copy the code into a file named bank_management_system.cpp.
  2. Open the terminal and navigate to the folder where the file is located.
  3. Compile the program using the following command: 
    g++ -o bank_management_system bank_management_system.cpp
  4. Run the compiled program 
    ./bank_management_system

Usage

  1. After running the program, you will be presented with a menu.
  2. Select the option you want to perform by entering the corresponding number.
  3. Follow the instructions to complete operations like creating a new account, depositing/withdrawing money, and more.
