C++ question:

A function that returns a special error code is usually better accomplished throwing an exception instead. The following class maintains an account balance: class Account { private: double balance; public: Account() { balance = 0; } Account(double initialDeposit) { balance = initialDeposit; } double getBalance() { return balance; } // returns new balance or -1 if error double deposit(double amount) { if (amount > 0) balance += amount; else return -1; // Code indicating error return balance; } // returns new balance or -1 if invalid amount double withdraw(double amount) { if ((amount > balance) || (amount

The gray part is the prompts, and the yellow part is standard output

Enter amount to deposit:10.00 $10 deposited Enter amount to withdraw:14.00 That is not a valid withdraw amount
