阅读短文，根据要求完成下面各小题。

Each year, many Chinese people go abroad because of all kinds of reasons. They are becoming younger and younger year by year. Even some Chinese parents send their children to foreign countries when they are only in a middle school. They think their children can get a wider view, less academic(学业) competition or family honor. But life can be hard for young people there. At first, they have to face the culture differences and language problems. However, these are not always the most difficult things to overcome(克服). To most children, controlling(管理) themselves well is a big challenge when studying alone in a strange country.

Yu Yang, a 15-year-old student from Guangdong Province studies in a high school in Toronto, Canada. 小题3To his surprise, his teachers there seldom push students to study hard. And usually there isn’t too much homework. Students have lots of free time to do some activities. Some of his friends spend their whole year’s money in the first two months of the new term. So they have to ask their parents for some more money.

On the one hand, studying abroad can help students learn foreign languages quickly and open up their eyes, but on the other hand, some children may feel lonely, become bad, lose themselves, etc. Many provlems may happen to them. These are different from their original thoughts.  小题4So parents should think them over before their children go abroad.

使用VC6打开考生文件夹下的工程test3_3，此工程包含一个源程序文件test3_3.cpp，其中建立了普通的基类base用于存储边的信息，建立派生类triangle和square，用于存储三角形和正方形的信息。按要求完成下列操作，将类定义补充完整。 (1)定义基类base的保护数据成员x和y用于记录边的长度，它们都是int型的数据。请在注释“//**1**”之后添加适当的语句。 (2)完成基类base默认构造函数的定义，把数据成员x和y分别初始化为参数a和b的值，要求使用作用域符“::”。请在注释“//**2**”之后添加适当的语句。 (3)完成派生类triangle函数disp的定义，使其以“三角形面积：”的格式将三角形的面积输出到屏幕上。请在注释“//**3**”之后添加适当的语句。 (4)添写派生类square的默认构造函数的定义，使其调用基类的构造函数，记录下正方形的边长信息a，其缺省值为0。请在注释“//** 4 **”之后添加适当的语句。 输出结果如下： 三角形面积：200 正方形面积：400 注意：除在指定位置添加语句之外，请不要改动程序中的其他内容。 源程序文件test3_3.cpp清单如下： #include＜iostream.h＞ class base { protected: //** 1 ** public: base(int a,int b) {//** 2 ** } virtual void disp(){cout＜＜"调用base基类"＜＜endl；) }; class triangle:public base { public: triangle(int a,int b):base(a,b){}; void disp() {//** 3 ** } }; class square:public base { public: //** 4 ** void disp(){cout＜＜"正方形面积:"＜＜x*y＜＜endl;} }; void main() { base *p; triangle t(20,20); square s(20); p=&t; p-＞disp(); p=&S; p-＞disp(); }
