Write a program that updates a binary file for customers in a bank. The data consist of a customer identity (an integer) and customer balance (a double value). Write two application files. In the first application program, create the binary file with identity (starting with 1000) and balances for five customers. In the second application program, let the balance be changed (using deposit or withdrawal) for some customers (update the file) and then print the contents of the file after updating.
