2. In this question we modify the bank account classes discussed in class so that the base class account has a method called write which sends the values of the members to a stream. This method is overridden in the derived classes to also send any new members to the stream.

class savingsaccount has the data member interestrate and the method addinterest. class chequingaccount has the data member remainingfreewithdrawals and overrides the withdraw method so that the withdrawal fee is not charged if remainingfreewithdrawls is positive.

Complete the implemenation (boxed in red) of the derived classes. To achieve code reuse, methods of the derived classes must utilize methods of the base classes.

For marking purposes, run the program and capture the screen output. Declaration of Classes AccountTypes
