Project_Name:- BANK MANAGNMENT SYSTEM Concepts_Used = Inheritance , Polymorphism

KEY_FEATURES

OOPS Object-Oriented Programming. It is a programming paradigm that utilizes the concept of "objects," which encapsulate data and behavior. The key principles of OOPS include encapsulation, inheritance, and polymorphism, providing a modular and organized approach to software development. OOPS facilitates the design and implementation of software systems by modeling real-world entities as objects with attributes and methods, promoting code reusability and maintainability.

PROJECT_INFO

OTP Class:
    The OTP class is designed to generate a one-time password with a specified expiration time (60 seconds in this case).
    It has methods to retrieve the OTP value (getValue()) and check if it has expired (isExpired()).

OTPManager Class:
    The OTPManager class is responsible for managing OTPs.
    It contains a pointer to an OTP object and functions to generate OTPs (generateOTP()) and verify them (verifyOTP()).

BankManagement Class:
    This class includes various functions for managing a bank account, such as checking account details, withdrawing funds, adding funds, transferring funds, generating a new card, checking card expiration, calculating annual interest, and providing emergency contact information.
    It uses the OTPManager class for generating and verifying OTPs during transactions.

Main Function:
    The main function serves as the entry point of the program.
    It prompts the user for a name and password, then checks if the provided credentials match predefined values. If correct, it allows the user to access the bank management system.
    Inside a loop, the user can choose various options based on the functionalities provided by the BankManagement class. The loop continues until the user decides to exit.
