Create a class called MyBoxes with: - 1 instance variable, and array to hold Box objects - a constructor with 1 parameter - the size of the array -- the constructor will create the array and set it to the size of the parameter - a method called emptyspace with no parameters -- the method returns how many elements of the array are null - a method called add with 3 parameters --- the method takes length, width and height as paremeters --- the method creates a Box object and adds it to the array if there is space left - a method called print with no parameters --- the method loops through the array and prints each element that is not null

Answer:

C++

Explanation:

class MyBoxes {

   private:

       // Pointer to Box object and array size. Required for dynamically creating an array.

       Box* boxes;

       int array_size;

       // Constructor

       MyBoxes(int array_size) {

           self.array_size = array_size;

           boxes = new Box[array_size] ;

       }

   public:

       // Methods

       int emptyspace() {

           int count = 0;

           for (int i=0; i < self.array_size; i++) {

               // Check for null

               if (!boxes[i])

                   count++;

           }

           return count;

       }

       void add(int length, int width, int height) {

           Box box1(length, width, height);

           if (self.emptyspace() == 0)  {

               self.addToArray(box1);

           }

       }

       void print() {

           Box *temporaryBox;

           for (int i=0; i < self.array_size; i++) {

               temporaryBox = boxes[i];

               if (temporaryBox) {

                   cout<<temporaryBox->length<<endl;

                   cout<<temporaryBox->width<<endl;

                   cout<<temporaryBox->height<<endl;

               }

           }

           // Free memory

           delete temporaryBox;  

       }
