第1题：

阅读以下说明和C++代码。
【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)五种状态。触发传输门状态转换的事件有click、complete和timeout三种。事件与其相应的状态转换如下图所示。
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，请填补代码中的空缺。
【C++代码1】
const int CLOSED=1； const int PENING=2；
const int PEN=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：
int state； //传输门当前状态
void setState(int state){ this-＞state=state；} //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(){
//此处代码省略，本方法输出状态字符串，
//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)；
PEN = 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(

正确答案：(1)state == CLOSED || state == CLOSING (2)state == OPENING || state == STAYOPEN (3)state == OPEN (4)state-＞click() (5)state-＞timeout() (6)state-＞complete() (7)door-＞setState(door-＞OPENING)
(1)state == CLOSED || state == CLOSING (2)state == OPENING || state == STAYOPEN (3)state == OPEN (4)state-＞click() (5)state-＞timeout() (6)state-＞complete() (7)door-＞setState(door-＞OPENING) 解析：本题考查的是状态转换图的程序设计与实现。
空(1)、(2)和(3)需要根据状态转换图来填写，空(1)、(2)和(3)所在的方法为click，表示当发生click事件时应该发生什么状态转换。根据代码可知，发生click事件时，状态分别跳转到OPENING，CLOSING和STAYOPEN，则发生click前的状态由状态转换图可以得到，分别为CLOSED或CLOSING、STAYOPEN或OPENING以及OPEN。
代码2中空(4)、(5)和(6)考查当发生click、timeout以及complete事件的时候，状态应该如何迁移。类Door的state成员变量用于记录类Door所处的状态，而state变量的类型为DoorState *，DoorState中分别具有click、timeout和complete方法用来响应对应的事件，因此，空(4)、(5)和(6)分别为：state-＞click()、state-＞timeout()和 state-＞complete()。
空(7)主要考查门的当前状态为CLOSED时，发生click事件时状态的迁移。根据状态图可知，CLOSED状态的在click事件下将迁移到OPENING，因此，此处应该将传输门状态设置为OPENING，DoorState变量存储了当前其存储的传输门的实例，因此，可直接调用其方法setState来设置状态，由于传输门状态采用类的实例变量表示，所以此处应该填写door-＞setState(door-＞OPENING)。
代码1和代码2的区别是：代码2将状态间的转换规则封装到具体的类中，当状态转换图的转换规则发生变化时，只需更改部分对应类中的状态迁移规则，而代码1中的迁移规则散落在程序中，维护起来较为困难。
第2题：

请认真阅读以下关于某传输系统的技术说明、状态转换图及C++代码，根据要求回答问题1和问题2。
【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 PENING = 2;
const int PEN = 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 s

正确答案：(1)state==CLOSED || state==CLOSING (2)state==OPENING || state==STAYOPEN (3)state==OPEN (4)state-＞click() (5)state-＞timeout() (6)state-＞complete() (7)door-＞setState(door-＞OPENING)
(1)state==CLOSED || state==CLOSING (2)state==OPENING || state==STAYOPEN (3)state==OPEN (4)state-＞click() (5)state-＞timeout() (6)state-＞complete() (7)door-＞setState(door-＞OPENING) 解析：这是一道要求读者掌握状态转换图的程序设计与实现的综合题。本试题的解答思路如下。
根据(1)空缺处所在的程序段给出的注释信息“发生click事件时进行状态转换”可知，(1)空缺处所在的方法为click，表示当发生click事件时应该发生什么状态转换。找出传输门响应事件与其状态转换图(见图6-18)与click事件相关的内容，并特别注意箭头所指的方向。由于发生click事件前的状态Closed、Closing分别跳转到状态Opening，因此(1)空缺处所填写的内容是“state == CLOSED || state == CLOSING”。
同理，由如图6-18所示中的状态转换关系可知，发生click事件前的状态Opening、Stayopen分别跳转到状态Closing，即(2)空缺处所填写的内容是“state == OPENING || state == STAYOPEN”；发生click事件前的状态Open跳转到状态StayOpen，即(3)空缺处所填写的内容是“state == OPEN”。
仔细阅读【C++代码2】程序段，由语句“private DoorState state=CLOSED;”可知，类Door的state成员变量用于记录类Door所处的状态，而state变量的类型为Doorstate*。由语句“virtual void click(){}”、“virtual void complete(){}”和“virtual void timeout(){}”可知，Doorstate中分别具有click、timeout和 complete方法用来响应对应的事件。根据(4)空缺处所在程序段“voidDoor::click()”可得，(4)空缺处所填写的内容是“state-＞click()”。
同理，根据(5)空缺处所在程序段“void Door::timeout()”可得，(5)空缺处所填写的内容是“state-＞timeout()”：根据(6)空缺处所在程序段“void Door::complete()”可得，(6)空缺处所填写的内容是“state-＞complete()”。
根据(7)空缺处所在程序段给出的注释信息“定义一个基本的Closed状态”和语句“void DoorClosed::click()”可知，(7)空缺处所填写的内容与传输门当前状态为Closed且发生Click事件时状态的迁移有关。结合如图6-18所示中的状态转换关系可知，在Click事件下Closed状态将迁移到Opening，因此(7)空缺处应该将传输门的状态设置为Opening。由于Doorstate变量存储了当前其存储的传输门的实例，因此可直接调用其方法setState设置状态。同时考虑到传输门的状态采用类的实例变量表示，故(7)空缺处所填写的内容为“door-＞setState(door-＞OPENING)”。
