Please answer .

Based on the header file for the class Array Bag below, which of the following is/are

A data field of the ADT data structure (as opposed to the interface)?

(select all that apply)

#ifndef _ARRAY_BAG #define _ARRAY_BAG #include "BagInterface.h" using namespace std; template class ArrayBag : public BagInterface { private: static const int DEFAULT_CAPACITY = 6; ItemType items[DEFAULT_CAPACITY]; int itemCount; int maxItems; int getIndexOf(const ItemType& target) const; public: ArrayBag(); int getCurrentSize() const; bool isEmpty() const; bool add(const ItemType& anEntry); bool remove(const ItemType& newEntry); void clear(); bool contains(const ItemType& anEntry) const; int getFrequencyOf(const ItemType& anEntry) const; vector toVector() const; }; #include "ArrayBag.cpp" #endif

Based on the textbook's implementation of the ArrayBag remove method (below), which of the following are steps of a successful remove function (the remove function returns True)? (Select all that apply).

template bool ArrayBag::remove(const ItemType& anEntry) { int locatedIndex = getIndexOf(anEntry); bool canRemoveItem = !isEmpty() && (locatedIndex > -1); if (canRemoveItem) { itemCount-; items[locatedIndex] = items[itemCount]; } // end if return canRemoveItem; } // end remove

Swap the anEntry value with the LAST value in the array.

Swap the anEntry value with the FIRST value in the array.

Overwrite the anEntry value in the array with the LAST value in the array.

Overwrite the anEntry value in the array with the FIRST value in the array.

Decrement the current count of bag items.

Increment the start position of the array.
