阅读下列说明和C++代码，将应填入(n)处的字句写在对应栏内。【说明】已知某企业欲开发一家用电器遥控系统，即用户使用一个遥控器即可控制某些家用电器的开与关。遥控器如左下所示。该遥控器共有4个按钮，编号分别是0至3，按钮0和2能够遥控打开电器1和电器2，按钮1和3则能遥控关闭电器1和电器2。由于遥控系统需要支持形式多样的电器，因此，该系统的设计要求具有较高的扩展性。现假设需要控制客厅电视和卧室电灯，对该遥控系统进行设计所得类图如右下所示。右上图中，类RomoteController的方法onPressButton(int button)表示当遥控器按键按下时调用的方法，参数为按键的编号；Command接口中on和off方法分别用于控制电器的开与关；Light中turnLight(int degree)方法用于调整电灯灯光的强弱，参数 degree值为0时表示关灯，值为100时表示开灯并且将灯光亮度调整到最大；TV中 setChannel(int channel)方法表示设置电视播放的频道，参数channel值为0时表示关闭电视，为1时表示开机并将频道切换为第1频道。【C++代码】class Light{ //电灯类public：void trunLight(int degree){//调整灯光亮度，0表示关灯，100表示亮度最大)；}；class TV{//电视机类public：vold setChannel(int channel]{//调整电视频道，0表示关机，1表示开机并切换到1频道}；}；class Command{//抽象命令类public：virtual void on()=0；virtual void off()=0；}；class RemoteController{ //遥控器类protected：Command* commands [4]；//遥控器有4个按钮，按照编号分别对应4个Command对象public：void onPressButton(int button){ //按钮被按下时执行命令对象中的命令if(button % 2==0)commands[button]-＞on()；else commands[button]-＞off()；}void setCommand(int button，Command* command){(1)=command；//设置每个按钮对应的命令对象}}；class LightCommand：public Command{ //电灯命令类protected： Light* light； //指向要控制的电灯对象public：void On(){light-＞trunLight(100)；)；void off()[light-＞(2)；)；LightCommand(Light * light){this-＞light=light；)；}；class TVCommand：public Command{//电视机命令类protected： TV*tv； //指向要控制的电视机对象public：void on(){tv-＞(3)；}；void off(){tv-＞setChannel(0)；)；TVCommand(TV *tv){this-＞tv=tv；)；}；void main(){Light light； TV tv；//创建电灯和电视对象LightCommand lightCommand (light)；TVCommand tVCommand(tv)；RemoteController remoteController；remoteController. setCommand(0，(4))； //设置按钮0的命令对象…//此处省略设置按钮1、按钮2和按钮3的命令对象代码}本题中，应用命令模式能够有效让类(5)和类(6)、类(7)之间的耦合性降至最小。
