Banking System

You are tasked with implementing a banking system in C++ that utilizes inheritance. You have a base class Account, a derived class SavingsAccount, and now, we'll introduce two more derived classes: CheckingAccount and CreditAccount.

Account Class: Create a base class called Account with the following attributes and methods:

• accountNumber (int)
• accountHolderName (string)
• balance (double)
• deposit(double amount) - Adds the specified amount to the balance.
• withdraw(double amount) - Subtracts the specified amount from the balance (if sufficient funds are available).
• displayAccountInfo() - Displays the account number, account holder's name, and current balance.

SavingsAccount Class: Create a derived class called SavingsAccount that inherits from Account. This class should have the following additional attributes and methods:

• interestRate (double) - Represents the annual interest rate.
• calculateInterest() - Calculates and adds interest to the account balance based on the formula: interest = balance * (interestRate / 100) / 12. This should be called once a month.
• Override the displayAccountInfo() method to include the interest rate.

CheckingAccount Class: Create another derived class called CheckingAccount that inherits from Account. This class should have the following additional attributes and methods:

• transactionFee (double) - Represents a fee charged for each withdrawal.
• applyTransactionFee() - Deducts the transaction fee from the account balance for each withdrawal.
• Override the withdraw(double amount) method to include the transaction fee.

CreditAccount Class: Create a third derived class called CreditAccount that inherits from Account. This class should have the following additional attributes and methods:

• creditLimit (double) - Represents the maximum negative balance allowed.
• Override the withdraw(double amount) method to check if the withdrawal amount exceeds the credit limit and handle it accordingly.

Your task is to write the C++ code for all four classes (Account, SavingsAccount, CheckingAccount, and CreditAccount) and demonstrate their functionality. Create objects of each class and perform operations to showcase their unique features. Ensure that you properly demonstrate the inheritance relationships between these classes.

Note: Provide the complete code for all four classes and a code snippet that demonstrates their usage, including deposits, withdrawals, interest calculation, and fee application. Handle the error conditions appropriately.

TestData

• SavingsAccount: 12344, "Ramaguru R", 1000.0, 5.0
• CheckingAccount: 54421, "Anu", 1500.0, 2.0
• CreditAccount: 181818, "Ammu", 500.0, 1000.0
• Deposit 200.0 in SavingsAccount
• Withdraw 1000.0 from CheckingAccount
• Withdraw 1000.0 from CheckingAccount
• Withdraw 500.0 from CreditAccount
• Withdraw 2000.0 from CreditAccount

After every deposit and withdraw print the account details.
