冒泡法

我要开始学习C＋＋了，今天把C里的冒泡法用C＋＋实现了一下

#include <string>
using namespace std;
//运动员类，姓名，学号，成绩（头文件）
class Athlete{
public:
           Athlete(string,int,float);
	  string getname();
	  int getid();
           float getscore();
private:
   string name;
   int id ;
   float score;
};

#include "athlete.h"
#include <string>
using namespace std;
Athlete::Athlete(string n,int i,float s){
name=n;
id=i;
score=s;
}
string  Athlete::getname(){
return name;
}
int Athlete::getid(){
return id;
}
float Athlete::getscore(){
return score;
}


// 冒泡法测试 对象排序  程序入口
#include "athlete.h"
#include <string>
#include <iostream>
using namespace std;

int main(){
	//建立一组对象用于排序
	Athlete ath[8]={
		Athlete("yubin",27,25.8),
			Athlete("zhangrui",34,34.56),
			Athlete("liuhai",37,21.24),
			Athlete("liema",25,67.34),
			Athlete("helin",38,45.67),
			Athlete("quchao",29,76.89),
			Athlete("lidian",36,87.75),
			Athlete("wanghai",14,53.27),
	};
	//   cout<<"the name is "<<ath[4].getname()<<endl;
	//   cout<<"the score is "<<ath[2].getscore()<<endl;
	
	//按对象组的成绩从大到小排列
	//外层循环
	for(int i=0;i<8;i++){
        //里层循环
		for(int j=i;j<8;j++){
            Athlete temp("default",0,0);
			//如果前面的成绩小于后者 则和后者调换
			if(ath[i].getscore()<ath[j].getscore()){
                temp=ath[i];
				ath[i]=ath[j];
				ath[j]=temp;
			}
		}
	}
	
    //输出排序后的名单
	for(i=0;i<8;i++){
		cout<<"name :"<<ath[i].getname()<<"  id :"<<ath[i].getid()<<"  score:"<<ath[i].getscore()<<endl;
	}
	return 0;
}

发错版了。把cpp当java用的话，还是用java吧。通篇的传值
