问题：

【说明】
传输门是传输系统中的重要装置。传输门具有Open(打开)、Closed(关闭)、Opening(正在打开)、StayOpen(保持打开)和Closing(正在关闭)5种状态。触发状态的转换事件有click、complete和timeout 3种，事件与其相应的状态转换如图6-18所示。

下面的【C++代码1】与【C++代码2】分别用两种不同的设计思路对传输门进行状态模拟，请填补代码段中的空缺语句。
【C++代码1】
const int CLOSED = 1; const int OPENING = 2;
const int OPEN = 3; const int CLOSING = 4;
const int STAYOPEN = 5; //定义状态变量，用不同整数表示不同状态
class Door
private:
private:
int state; //传输门当前状态
void setState(int state) this-＞state = stale;//设置当前状态
public:
Door () :state (CLOSED) ;
void getState() //根据当前状态输出相应的字符串
switch(state)
case OPENING: cout ＜＜"OPENING" ＜＜ endl;break;
case CLOSED: cout ＜＜ "CLOSED" ＜＜ endl;break;
case OPEN: cout ＜＜ "OPEN" ＜＜ endl; break;
case CLOSING: cout ＜＜ "CLOSING" ＜＜ endl; break;
case STAYOPEN: cout ＜＜ "STAYOPEN" ＜＜ endl; break;


void click()//发生click事件时进行状态转换
if ( (1) ) setState(OPENING);
else if ( (2) ) setState(CLOSING);
else if ( (3) ) setState(STAYOPEN);

void timeout()//发生timeout事件时进行状态转换
if (state == OPEN) setState(CLOSING);

void complete() //发生complete事件时进行状态转换
if (state == OPENING) setState(OPEN);
else if (state == CLOSING) setState(CLOSED);

;
int main()
Door aDoor;
aDoor.getState(); aDoor.click(); aDoor.getState(); aDoor.complete();
aDoor.getState(); aDoor.click(); aDoor.getState(); aDoor.click();
aDoor.getState(); return 0;

【C++代码2】
class Door
public:
DoorState *CLOSED, *OPENING, *OPEN, *CLOSING, *STAYOPEN, *state;
Door();
virtual ～Door() ... //释放申请的内存，此处代码省略;
void setState(DoorState *state) this-＞state = state;
void getState()
//例如，当前状态为CLOSED时，输出字符串为"CLOSED"
;
void click();
void timeout();
void complete();
;
Door::Door()
CLOSED = new DoorClosed(this);
OPENING = new DoorOpening(this);
OPEN = new DoorOpen(this);
CLOSING = new DoorClosing(this);
STAYOPEN = new DoorStayOpen(this);
state = CLOSED;

void Door::click() (4) ;
void Door::timeout() (5) ;
void Door::complete() (6) ;
class DoorState //定义一个抽象的状态，它是所有状态类的基类
protected: Door *door;
public:
DoorState(Door *door) this-＞door = door;
virtual ～DoorState(void);
virtual void click()
virtual void complete()
virtual void timeout()
;
class DoorClosed :public DoorState //定义一个基本的closed状态
public:
DoorClosed(Door *door):DoorState(door)
virtual ～ DoorClosed ()
void click();
;
void DoorClosed::click() (7) ;
//其他状态类的定义与实现代码省略
iht main()
Door aDoor;
aDoor.getState(); aDoor.click(); aDoor.getState(); aDoor.complete();
aDoor.getState(); aDoor.timeout(); aDoor.getState(); return 0;

【问题2】
请用150字以内的文字简要说明【C++代码1】、【C++代码2】这两种对传输门进行状态模拟的设计思路的区别之处。
