BankAccount Withdraw Exception

Create a class BankAccount with a private double balance.

Requirements: 1. Constructor BankAccount(double initialBalance): throws std::invalid_argument with "Initial balance cannot be negative" if initialBalance < 0. Otherwise sets balance. 2. void deposit(double amount): throws std::invalid_argument with "Deposit amount must be positive" if amount <= 0. Otherwise adds to balance. 3. void withdraw(double amount): throws std::invalid_argument with "Withdraw amount must be positive" if amount <= 0; throws std::runtime_error with "Insufficient funds" if amount > balance. Otherwise subtracts from balance. 4. double getBalance() const: returns the current balance.
