Chapter 18.6, Problem 18.19CP
Program Plan Intro
Generic class:
- It is a class in which the class name is followed by the type parameter section.
- In generic class, one or more type arguments are separated by commas.
- The programmers are enabled to specify a single class declaration with a set of related type.

Why do we use generic classes?
Generic classes allows for code reuse (for different data types)
Generic classes allows for the Object class (the generic data type) to be used as
a field
Generic classes allow for abstract class (of which there can be no instantiations)
to be used as a field
The compiler will automatically generate test cases based on the appropriate
data types
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)…
