Define the class bankAccount to implement the basic properties of a bank account. An object of this class should store the following data: Account holderâs 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 func- tions to manipulate an object. Use a static member in the class to automatically assign account numbers. Also declare an array of 10 compo- nents of type bankAccount to process up to 10 customers and write a program to illustrate how to use your class.
