template< class NODETYPE >

class List

{

public:

	List();		//constructor

	~List();		//destructor

	void insertAtFront( const NODETYPE & );

	void insertAtBack( const NODETYPE & );

	bool removeFromFront( NODETYPE & );

	bool removeFromBack( NODETYPE & );

	bool isEmpty() const;

	void print() const;

private:

	ListNode< NODETYPE > *firstPtr;		//pointer to first node

	ListNode< NODETYPE > *lastPtr;		//pointer to last node



	//Utility function to allocate a new node

	ListNode< NODETYPE > *getNewNode( const NODETYPE & );

};



//Default constructor

template< class NODETYPE >

List< NODETYPE >::List() 

	: firstPtr( 0 ), lastPtr( 0 ) { }	//问题，数据成员*firstPtr和*lastPtr, 初始化写成 : *firstPtr(0), *lastPtr(0) 报错,为什么加指针符号就不对?
