阅读以下说明和c++代码，将应填入(n)处的字句写在对应栏内。【说明】现要编写一个画矩形的程序，目前有两个画图程序：DP1和DP2，DP1用函数draw_a_line(x1， y1，x2，y2)画一条直线，DF2则用drawline(x1，x2，y1，y2)画一条直线。当实例画矩形时，确定使用DP1还是DP2。为了适应变化，包括“不同类型的形状”和“不同类型的画图程序”，将抽象部分与实现部分分离，使它们可以独立地变化。这里，“抽象部分”对应“形状”，“实现 部分”对应“画图”，与一般的接口(抽象方法)与具体实现不同。这种应用称为Bridge(桥接)模式。图9-7显示了各个类间的关系。这样，系统始终只处理3个对象：Shape对象、Drawing对象、DP1或DP2对象。以下是 C++语言实现，能够正确编译通过。【C++代码】class DP1{public:static void draw_a_line(double x1, double y1,double x2, double y2){//省略具体实现});class DP2{public:static void drawline(double x1, double x2,double y1, double y2){//省略具体实现}};class Drawing{public:(1) void drawLine(double x1,double y1,double x2,double y2)=0;};class V1Drawing:public Drawing{public:void drawLine(double x1, double y1,double x2, double y2){DP1::draw_a_line(x1,y1,x2,y2);}};class V2Drawing:public Drawing{public:void drawLine(double x1, double y1, double x2, double y2){(2);}};class Shape{private:(3) _dp;public:Shape(Drawing *dp);virtual void draw()=0;void drawLine(double x1, double y1, double x2, double y2);};Shape::Shape(Drawing *dp){_dp = dp;}void Shape::drawLine(double x1, double y1, double x2, double y2){ //画一条直线(4);}class Rectangle: public Shape{private:double _x1,_y1,_x2,_y2;public:Rectangle(Drawing *dp, double x1, double y1,double x2, double y2);void draw();};Rectangle::Rectangle(Drawing *dp, double x1, double y1, double x2, double y2):(5){_x1=x1;_y1=y1;_x2=x2;_y2=y2;}void Rectangle::draw(){//省略具体实现}
