A program to simulate a simple banking system in which the initial balance and rate of interest are read from the keyboard and these values are initialised using the constructor member function. The program consists of the following methods:To initialise the balance amount and the rate of interest using constructor member functionTo make depositTo withdraw an amount for the balanceTo find compound interest based on the rate of interestTo know the balance amountTo display the menu options

Sure, here is a simple Python program that simulates a basic banking system:

class BankAccount:
    def __init__(self, balance, interest_rate):
        self.balance = balance
        self.interest_rate = interest_rate

    def deposit(self, amount):
        self.balance += amount
        return self.balance

    def withdraw(self, amount):
        if amount > self.balance:
            print("Insufficient funds")
        else:
            self.balance -= amount
        return self.balance

    def compound_interest(self):
        self.balance = self.balance * (1 + self.interest_rate)
        return self.balance

    def get_balance(self):
        return self.balance

    def display_menu(self):
        print("1. Deposit")
        print("2. Withdraw")
        print("3. Calculate compound interest")
        print("4. Check balance")
        print("5. Exit")

def main():
    balance = float(input("Enter initial balance: "))
    interest_rate = float(input("Enter interest rate: "))
    account = BankAccount(balance, interest_rate)

    while True:
        account.display_menu()
        choice = int(input("Enter your choice: "))

        if choice == 1:
            amount = float(input("Enter amount to deposit: "))
            account.deposit(amount)
        elif choice == 2:
            amount = float(input("Enter amount to withdraw: "))
            account.withdraw(amount)
        elif choice == 3:
            account.compound_interest()
        elif choice == 4:
            print("Current balance: ", account.get_balance())
        elif choice == 5:
            break
        else:
            print("Invalid choice. Please choose a valid option.")

if __name__ == "__main__":
    main()

This program creates a BankAccount class with methods for depositing, withdrawing, calculating compound interest, checking the balance, and displaying a menu. The main function initializes a BankAccount object with user input for the initial balance and interest rate, then enters a loop where the user can choose to deposit, withdraw, calculate compound interest, check the balance, or exit the program.
