【说明】
在一个简化的绘图程序中，支持的图形种类有点(point)和圆(circle)，在设计过程中采用面向对象思想，认为所有的点和圆都是一种图形(shape)，并定义了类型shape t、 point t和circle t分别表示基本图形、点和圆，并且点和圆具有基本图形的所有特征。
【C代码】
typedef enum point,circle shape type; /* 程序中的两种图形：点和圆 */
typedef struct /* 基本的图形类型 */
shape_type type; /* 图形中类标识：点或者圆*/
void (*destroy) （ ）; /* 销毁图形操作的函数指针*/
void (*draw) （ ）; /* 绘制图形操作的函数指针*/
shape_t;
typedef struct shape_t common; int x; iht y; point_t; /* 定义点类
型, x, y为点坐标*/
void destroyPoint (point_t* this) free (this); printf ("Point destoryed!
/n"); ) /* 销毁点对象*/
void drawPoint(point_t* this) printf("P(%d,%d)", this->x, this->y);
/* 绘制点对象*/
shape_t* createPoint (va_list* ap) (/* 创建点对象，并设置其属性*/
point_t* p_point;

[简答题]Once a circle missed a wedge. The circle wanted to be whole, so it went around looking for its missing piece. But because it was incomplete and therefore could roll only very slowly, it admired the flowers along the way. It chatted with worms. It enjoyed the sunshine. It found lots of different pieces, but none of them fit. So it left them all by the side of the road and kept on searching. Then one day the circle found a piece that fit perfectly. It was so happy. Now it could be whole, with nothing missing. It incorporated the missing piece into itself and began to roll. Now that it was a perfect circle, it could roll very fast, too fast to notice flowers or talk to the worms. (46) When it realized how different the world seemed when it rolled so quickly, it stopped, left its found piece by the side of the road and rolled slowly away.
(47) The lesson of the story, I suggested, was that in some strange sense we are more whole when we are missing something. The man who
