In this post, we will create a C++ Bank Management System Project with source code and step by step explanation of how to use it. The system will allow users to create accounts, deposit and withdraw money, check balances, list all account holders, modify account details, and close accounts. This project will be console-based and is suitable for beginners learning C++.
What is a Bank Management System?
A Bank Management System is a software application that allows banks to manage and organize their customer accounts efficiently. It simplifies various banking operations such as account creation, deposit, withdrawal, and account maintenance.
Overview of C++ Bank Management System Project
In this Bank Management System project, we will implement the following features:
- New Account Creation: Users can create new bank accounts.
- Deposit Amount: Users can deposit money into their accounts.
- Withdraw Amount: Users can withdraw money from their accounts.
- Balance Enquiry: Users can check their account balances.
- List of All Account Holders: The system will display a list of all existing account holders.
- Close an Account: Users can close their accounts.
- Modify an Account: Users can update their account details.
Now, let’s see the step-by-step working of that Bank Management System project in C++.

Code Explanation
The C++ code for the Bank Management System project consists of a class named account that represents a bank account. It includes functions for creating an account, displaying account details, modifying account information, depositing, and withdrawing money.
The main function acts as the program’s entry point, providing a menu-driven interface for users to choose different banking operations.
