Is-A Relationship

A base class Account has been provided with a protected double balance, a constructor, and a getBalance() function.

A derived class SavingsAccount publicly inherits from Account and has an additional double interestRate. The constructor has already been implemented.

Your task is to implement the calculateInterest() function. It should return balance * interestRate.

Do NOT include a main function. Your code will be tested automatically.
