Bank Management System
A brief description of what this project.
Key Features of Your System:
Account Management: Users can create new accounts, log in, and perform transactions securely.
Gift Card Integration: Supports gift card creation, top-up, and redemption.
Reward Points System: Allows users to earn and redeem points based on transactions.
Transaction History: Maintains a log of all user transactions.
Data Persistence: Saves account and transaction data to text files for continuity.
User Interface: Utilizes console-based UI with color-coded messages for better user experience.
Object Oriented Concepts implementation:
- Core Functionalities Account Management: Users can create accounts, log in, deposit, withdraw, and view transaction histories.
Gift Card System: Users can generate gift cards, top them up, and redeem purchases using reward points.
Reward Points: Points are earned based on transaction amounts and can be redeemed for discounts.
Transaction Logging: All operations are logged to files, ensuring persistence and traceability.
- Object-Oriented Design Base Class: Account Attributes: Stores account number, username, password, encrypted password, and balance.
Methods:
createAccount(): Prompts user input to create a new account and saves it to a file.
login(): Validates user credentials against stored data.
deposit(float amt): Adds funds to the account.
withdraw(float amt): Subtracts funds, with error handling for insufficient balance.
transactionHistory(): Displays a list of past transactions.
save(): Updates account information in the storage file.
logTransaction(string type, float amt): Records each transaction to a history file.
Derived Class: GiftCard Additional Attribute: Holds a unique cardID for each gift card.
Methods:
createGiftCard(): Generates a new gift card ID.
topUp(float amount): Adds funds to the gift card.
displayDetails(): Shows account and gift card information.
Further Derived Class: RedeemPoints Additional Attribute: Manages points earned through transactions.
Methods:
earnPoints(float amount): Calculates and adds points based on the transaction amount.
redeem(float purchaseAmount): Allows users to redeem points for purchases.
redeem(int pts): Redeems a specified number of points for a discount.
showPoints(): Displays the current points balance.
displayDetails(): Shows detailed account information, including points.
Additional Classes Notifier: Handles user notifications with customizable messages and colors.
AdvancedAccount: Extends Account and Notifier, overriding the deposit method to include notifications.
Operation (Abstract Base Class): Defines a contract for operations like deposit and withdrawal.
DepositOperation: Implements deposit functionality.
WithdrawOperation: Implements withdrawal functionality.
RedeemOperation: Implements redemption of points for purchases.
- Key Concepts Demonstrated Polymorphism: Achieved through virtual functions and abstract classes, allowing for dynamic dispatch of methods like perform() in operation classes.
Encapsulation: Sensitive data like passwords are handled securely, and account details are managed through getter and setter methods.
Abstraction: Complex operations are abstracted into classes and methods, providing a clear interface for users.
Inheritance: Allows for code reuse and extension, as seen in the GiftCard and RedeemPoints classes inheriting from Account. en.wikipedia.org
- User Interface Splash Screen: Displays a welcome message with a loading animation.
Main Menu: Offers options to create an account, log in, or exit the system.
User Menu: Provides authenticated users with options to perform various account operations.
Input Validation: Ensures that user inputs are of the correct type and handles errors gracefully.
- File Handling Account Storage: Account information is stored in accounts.txt.
Transaction History: Each account has a corresponding history file named _history.txt.
Data Persistence: Changes to account balances and transaction logs are saved back to the respective files.
- Enhancements and Considerations Security: Implementing stronger encryption for passwords and sensitive data.
Error Handling: Adding more robust exception handling and input validation.
User Experience: Improving the user interface with better formatting and clearer prompts.
Scalability: Considering the use of databases for handling larger volumes of data.
