}
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;
