Challenge: Bank Account Withdrawal
Challenge Overview:
You will build a simple BankAccount class in C++ that supports withdrawing funds. If a withdrawal request exceeds the available balance, your code must throw a custom exception named InsufficientFundsException. This exercise helps you practice creating and using your own exception types to handle error conditions in a realistic scenario.
Key Requirements:
- Define a custom exception type,
InsufficientFundsException, that inherits fromstd::exceptionand overrides thewhat()method to return the message"Insufficient funds". - Implement a
BankAccountclass with:- A constructor to set the initial balance;
- A
withdraw(double amount)method that throws anInsufficientFundsExceptionifamountis greater than the current balance; otherwise, it subtractsamountfrom the balance.
Example usage:
BankAccount account(100.0);
account.withdraw(50.0); // OK
account.withdraw(60.0); // Throws InsufficientFundsException

Build two classes to simulate a bank account withdrawal scenario with custom exception handling:
- Define a custom exception type that inherits from
std::exceptionand overrides thewhat()method to return a specific message when an error occurs. - Create a class to represent a bank account with a balance. Include a constructor for setting the initial balance and a method for withdrawing funds. If the withdrawal amount exceeds the available balance, your method must throw your custom exception; otherwise, it should deduct the amount from the balance.
Focus on using clear class and method names. Ensure your exception message is easy to identify. Follow best practices for exception handling and class design.

Can you show me how to define the InsufficientFundsException class?
How should I implement the withdraw method to throw the exception?
Can you explain how exception handling works in this scenario?
Awesome!
