01. ArrayBag - Embedded Coding Lab Requested files: Baginterface.h, ArrayBag.cpp, Bag_test.cpp (Download) Maximum number of files: 8 Type of work: Individual work Create a class ArrayBag derived from Baginterface which implements the Bag Abstract Data Type (ADT). Baginterface.h defines the following public interface functions: 1. Bago - Create and Empty Bag 2. void additem(ltem item) - add an item to the Bag 3. boolean isEmpty() - indicate whether or not the bag is empty 4. int size() - return the number of items in the Bag Once you have created your bag, print a report of the bag size. There is a binary file of signed 32-bit integers in Little- Endian format. Your test program must open this file and insert all the integers into a bag using the interface functions. Print a report of the gag size
