operator [] linkedList

[Dekker1]

Is this the right way to to overloading for the operator[]?

  template<class T>
T LinkedList<T>::operator[](int index)
{
	Node<T>* nodePtr;
	Node<T>* nodeReturn;
	int count = 0;
	nodePtr = head;
	
	if(nodePtr == NULL)
	{
		throw "The list is empty";
	}
	
	while(nodePtr != NULL)
	{
		count++;
		if(index > count)
		{
			throw "Invalid index.";
		}
	}
	
	
        nodePtr = head;
	if((index > 0))
	{
		while(nodePtr != NULL)
		{
			if(count == index)
			{
				nodeReturn = nodePtr;
				nodePtr = nodePtr->next;
				return nodePtr->data;
			}
			count++;
			
			
		}
	}
	else
	{
		throw "Invalid index.";
	}
}
