[after §15.7] In a binary file, carriage-return and new-line characters have no special function in reading or writing operations—they are just like any other characters. (T / F).
[after §15.8] Grocery Store Inventory:
Enhance the grocery-store Inventory program created in a Chapter 13 project by providing a FileHandler class that contains write and read methods to write an object to a file in the local directory or read an object from a file in the local directory. Complete the following skeleton by providing the needed code fragments. You don’t actually need the Chapter 13 grocery store Inventory program to do this exercise. You can test this new class with any appropriately instantiated object. The class that defines that object must, however, include a certain special feature. How would you modify the Inventory class to incorporate that special feature?
