使用VC6打开考生文件夹下的工程test42_3。此工程包含—个test42_3.cpp，其中定义了类Cpolygon、COutput和CTriangle，其中CTriangle类由Cpolygon和COutput类public派生，但三个类的定义并不完整。请按要求完成下列操作，将程序补充完整。

(1)定义类CPolygon的保护数据成员width和height，它们都是int型的数据。请在注释“//**1**”之后添加适当的语句。

(2)完成类CPolygon的成员函数set_values(int a，int b)，使参数a和b分别赋值给保护数据成员width和height，请在注释“//**2**”之后添加适当的语句。

(3)完成类Coutput的成员函数output(int)的定义，将传入的参数为血型的i输出到屏幕并换行，请在注释“//**3**”之后添加适当的语句。

(4)完成派生类CTriangle的声明，它由Cpolygon和COutput类public派生，请在注释“//**4**”之后添加适当的语句。

源程序文件test42_3.cpp清单如下：

include ＜iostream.h＞

class CPolygon

{

protected:

// ** 1 **

public:

void set_values(int a, int b)

{

// ** 2 **

}

};

class COutput

{

public:

void output(int i);

};

void COutput::output(int i)

{

// ** 3 **

}

// ** 4 **

{

public:

int area (void)

{

return (width * height / 2);

}

}

int main ()

{

CTriangle trgl;

trgl.set_values (4,5);

trgl.output (trgl.area());

return 0;

}
