Question

In C++, define the class bankAccount to implement the basic properties of a
bank account. An object of this class should store the following data:
Account holder’s name (string), account number (int), account type
(string, checking/saving), balance (double), and interest rate (double).
(Store interest rate as a decimal number.) Add appropriate member functions
to manipulate an object. Use a static member in the class to
automatically assign account numbers. Also declare an array of 10 components
of type bankAccount to process up to 10 customers and write a
program to illustrate how to use your class.
