并将答案填在标号为31-40的相应位置。

In country after country, talk of nonsmokers’ right is in the air. While a majority of countries have taken little or   31   action yet, some 30 nations introduced steps based on the law to control smoking. Many laws have been made in other   32   to help clear the air for nonsmokers, or to cut the quantity of cigarettes.

In some developed countries the quantity of cigarettes has become more or less fixed. However, in many   33   (develop) nations, smoking is seen as a sign of economic progress – and is   34  encouraged. As more tobacco companies go international, new markets are sought to gain new   35   in those countries. For example, great efforts are made by the American tobacco industry to sell cigarettes in Middle East and North Africa,   36   sales of tobacco increased by more than 27 percent in 1974.

World government should lead the battle   37   smoking. Limitations on cigarette advertisements, plus health warnings on packages and forbidding public smoking in certain places, are   38   most popular tools used by nations in support of nonsmoker or controlling smoking. But world attention also is being paid to another step which will make the smoker increasingly self-conscious (自觉的) and uncomfortable about his habit. Great efforts should   39   (make) to inform young people especially of the shocking results of taking up the habit. And cigarette price should be raised.

In the long run,   40   is no doubt that everybody would be much better-off if smoking were forbidden altogether, but people are not ready for such strong action.

使用VC6打开考生文件夹下的工程test7_3,此工程包含一个源程序文件test7_3.cpp,其中含有一个类Circle的定义,但该类的定义并不完整。请按要求完成下列操作,将类Circle的定义补充完整。
(1)为类Circle增加一个构造函数,该函数有一个参数,并在构造时将该参数值赋给成员radius。将该函数实现为一个非内联函数,并且使用参数列表的方式将类成员赋值。请在注释“//**1**”之后添加适当的语句。
(2)为类Circle增加一个成员函数print(),使得可以输出有关圆的信息,比如下列程序
Circle c;
c.SetRadius(5);
c.Print();
将输出:The circle has radius of 5!
请在注释“//**2**”之后添加适当的语句。
(3)完成友元函数void CompareR(Circle *cl,Circle*c2)的定义,在屏幕中输出c1与c2比较radius大小结果,要求使用 if-else结构完成。请在注释“//**3**”之后添加适当的语句。
输出结果如下;
The circle has radus of 5!
The circle has radius of 10!
c1<c2
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test7_3.cpp清单如下:
#include<iostream.h>
class Circle
public:
Circle():radius(5)
//**1**
void SetRadius(int r) radius=r;
int GetRadius() return radius;
//**2**
friend void CompareR(Circle *c1,Circle*C2);
private:
int radius;
;
void CompareR(Circle *c1,Circle *C2)

//**3**
cout<<"c1>c2"<<endl;
else
if((c1->GetRadius())==(c2->GetRadius()))
cout<<"c1=c2"<<endl;
else
if((c1->GetRadius())<(c2->GetRadius()))
cout<<"c1<c2"<<endl;

void main()

Circle c1;
c1.SetRadius(5);
C1.Print();
Circle c2(10);
c2.Print();
CompareR(&c1,&c2);
