Before India gained independence (独立), a few young men from the villages wanted to free India from the foreign rule; they wanted the British to quit India. They needed material wealth to 36 the British out of India, so they started collecting 37 in the Indian villages.

[说明]

某绘图系统存在Point、Line和Square 3种图元，它们具有Shape接口，图元的类图关系如图8-5所示。

现要将Circle图元加入此绘图系统以实现功能扩充。已知某第三方库已经提供了XCircle类，且完全满足系统新增的Circle图元所需的功能，但XCircle不是由Shape派生而来的，它提供的接口不被系统直接使用。[C++代码1]既使用了Xcircle，又遵循了Shape规定的接口，既避免了从头开发一个新的Circle类，又可以不修改绘图系统中已经定义的接口。[C++代码2]根据用户指定的参数生成特定的图元实例，并对其进行显示操作。
该绘图系统定义的接口与XCircle提供的显示接口及其功能如表8-2所示。

[C++程序代码1]
class Circle:public (1)
Private:
(2) m_circle;
public:
void display()
m_circle. (3)

;

[C++程序代码2]

class Factory
public:
(4) getShapeInstance(int type) //生成特定类实例
switch(type)
case 0:return new Point;
case 1:return new Rectangle;
case 2:return new Line;
case 3: return new Circle;
default: return NULL;

;
void mainint argc,char *argv[])
if(argc !=2)
cout＜＜"error parameters!"＜＜end1;
return;

int type=atoi(argv[1]) :
Factory factory;
Shape *s;
s=factory. (5) ;
if(s==NULL)
cout＜＜"Error get the instance!"＜＜end1;
return;

s-＞display();
(6) ;
return;
