1) Class definition:-Define a 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, check/savings/business)

·Balance (double)

·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.

2) Implement all appropriate member functions of a class.

3) write a program that illustrate how to use your class. Your program should have the following:-Declare an array of 20 components of type bankAccount to process up to 20 customers.

·void menu() – helps the user to select if the customer is new or if they already exist. Furthermore, it prints the customer’s data or exits the program.

·Use a switch statement which uses the value from menu() as an expression to call the following user-defined functions:

void addCustomber() – this function enters/adds the customer details. You may call one mutator function (setter) of a class in this function.

void processCustomer() – this function calls the search() function. It also calls and uses subMenu() function as an update and priming read. Furthermore, it uses the switch statement to call the other three class member functions to process the deposit, withdrawal, and print.

void printCustomersData() – print all information of the customers. 

·void submenu() – help the user to select between making a deposit, withdrawal, checking balance or exiting the submenu.

·int search() – search the customer’s details by using the customer’s account number. You may call one accessor function (getter) of a class in this function.

·main() function – this has the switch statement to call addCustomber(), processCustomer() and printCustomersData().

Hint: The listed user-defined functions are not the same as the class member functions. However, the user-defined functions can call the class member functions. The array that stored 20 components should be used as a parameter to access and process the customers’ details.
