Bank Management System Project in C++ Using Data Structures

This article will guide you through creating a simple Bank Management System (BMS) project in C++ using various data structures. This project will demonstrate fundamental concepts like data storage, manipulation, and basic banking operations, providing a foundation for further development.

Project Requirements

Before diving into the code, let's define the basic functionalities of our BMS:

Account Management:
- Create new accounts (Savings/Current)
- Deposit money
- Withdraw money
- Check balance
- View account details
- Update account information (e.g., address)
Customer Management:
- Add new customer
- View customer details
- Update customer information
Transaction History:
- Record all transactions
- View transaction history

Data Structures in C++ for BMS

We'll employ several data structures in C++ to effectively manage the data for our BMS:

Structures: To represent customer and account details (e.g., Customer, Account).
Arrays: To store multiple customer or account records.
Linked Lists: To manage the transaction history, allowing for efficient insertion and retrieval of recent transactions.

Implementation Steps

Define Data Structures:
- Create structures for Customer and Account.
- Include essential attributes like:
  - Customer: Name, Address, Phone Number, etc.
  - Account: Account Number, Account Type, Balance, etc.
Create Account Management Functions:
- createAccount(): To add a new account.
- deposit(): To add funds to an account.
- withdraw(): To withdraw funds from an account.
- checkBalance(): To display the current balance.
- viewAccountDetails(): To display all account information.
- updateAccount(): To modify account details.
Create Customer Management Functions:
- addCustomer(): To add a new customer.
- viewCustomerDetails(): To display customer details.
- updateCustomer(): To modify customer information.
Transaction History Management:
- Implement a linked list to store transactions.
- Create a function to add transactions to the linked list.
- Create a function to display the transaction history.
Main Function:
- Use a menu-driven approach to interact with the user.
- Call appropriate functions based on the user's choice.
- Implement error handling and validation for user input.

Example Code Snippets

Data Structures:

struct Customer {
    int customerId;
    string name;
    string address;
    // ... other customer details
};

struct Account {
    int accountId;
    int customerId;
    string accountType;
    double balance;
};

Transaction History Linked List (Simplified):

struct Transaction {
    int accountId;
    char type; // 'D' for deposit, 'W' for withdrawal
    double amount;
    Transaction *next;
};

Sample Function:

// Function to create a new account
void createAccount() {
    Account newAccount;
    // Get account details from user
    // ...
    // Add newAccount to the account array
    // ...
    cout << "Account created successfully!" << endl;
}

Conclusion

This project provides a basic understanding of building a Bank Management System using C++ and data structures. You can expand this project by:

Implementing more sophisticated security features (like user authentication).
Adding additional functionalities like loan management or interest calculations.
Utilizing file storage to persist data between program runs.

Remember to thoroughly test your code and handle potential errors to ensure a robust and user-friendly system.
