Write on C++ Program Please.#1. InstructionsDefine 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.Example output is shown below:1: Enter 1 to add a new customer.                                   2: Enter 2 for an existing customer.                                3: Enter 3 to print customers data.                                 9: Enter 9 to exit the program.                                     1                                                                    Enter customer’s name: Dave Brown                                   Enter account type (checking/savings): checking                     Enter amount to be deposited to open account: 10000                 Enter interest rate (as a percent): .01                             1: Enter 1 to add a new customer.                                   2: Enter 2 for an existing customer.                                3: Enter 3 to print customers data.                                  9: Enter 9 to exit the program.                                     3                                                                   Account Holder Name: Dave Brown                                     Account Type: checking                                               Account Number: 1100                                                Balance: $10000.00                                                  Interest Rate: 0.01%                                                *****************************                                       1: Enter 1 to add a new customer.                                   2: Enter 2 for an existing customer.                                3: Enter 3 to print customers data.                                  9: Enter 9 to exit the program.                                     9Since your program handles currency, make sure to use a data type that can store decimals with a precision to 2 decimals.
