1. Why do you need to implement all the methods of an interface in class which implements an interface?

Describe how you can use an interface as an alternative to a class to specify the type for a parameter.

Design a generic class to hold the following information about a bank account. - Balance, number of deposits this month, number of withdrawals, annual interest rate, monthly service charges. The class should have the following member functions constructor: accepts arguments for the balance and annual interest rate deposit: A virtual function that accepts an argument for the amount of the deposit. The function should add the argument to the account balance. It should also increment the variable holding the number of deposits. withdraw: A virtual function that accepts an argument for the amount of the deposit. The function should subtract the argument to the account balance. It should also increment the variable holding the number of deposits. calcInt: A virtual function that updates the balance by calculating the monthly interest earned by the account, and adding this interest to the balance. This is performed by the following formulas: Monthly Interest Rate = (Annual Interest Rate /12)…
