int List::deleteLast() {
	if (currentSize != 0) {
		int tmp = last->getContent();
		ListItem *del = last;
		last = del->getPrevious();
		delete del;
		currentSize--;
		return tmp;
	}
	else
		return 0;
}

Example #2

void List::insertElementAt(int i, int pos) {
	if (pos <= 0)
		prependElement(i);
	else if (pos >= getSize())
		appendElement(i);
	else {
		ListItem *tmp = first;
		while (pos-- > 0) {
			tmp = tmp->getNext();
		}
		new ListItem(tmp->getPrevious(), tmp, i);
		currentSize++;
	}
}
