题目：  
//5个选手，10个评委  
//10个评委给每个选手打分，去掉最高分和最低分，再取平均值就是最终的得分  
//最后再给每个选手按分数排序

#include "stdafx.h"
    #include <string>
    #include <iostream>
    #include <vector>
    #include <deque>
    #include <algorithm>
    using namespace std;
    
    
    
    class Player
    { 
    public:	
    	Player(string name,int score):m_score(score),m_name(name)
    	{ 
    
    	}
    
    	int m_score;
    	string m_name;
    };
    
    //构造选手
    void SetPlayer(vector<Player> & player)
    { 
    	string str1 = "ABCDE";
    	for (int i = 0; i < 5; i++)
    	{ 		
    		string str2 = "Player";
    		str2 +=str1[i];
    		Player p(str2, 0);   //PlayerA PlayerB......
    		player.push_back(p);
    	}
    }
    
    
    // 打分
    void SetScore(vector<Player> & player)
    { 
    	for (vector<Player>::iterator it = player.begin(); it != player.end(); it++)
    	{ 
    		deque<int> deq_s;
    		for (int j = 0; j < 10; j++)  //10个评委打分
    		{ 
    			int scorexx = rand() % 41 + 60;   //60-100
    			deq_s.push_back(scorexx);
    		}
    		
    		sort(deq_s.begin(), deq_s.end());  //排序
    
    		deq_s.pop_back();             //去掉最高分和最低分
    		deq_s.pop_front();
    
    		int sum=0;
    		for (deque<int>::iterator itd = deq_s.begin(); itd != deq_s.end(); itd++)
    		{ 
    			 sum += (*itd);
    		}
    
    		int average=sum / deq_s.size(); //求平均值
    
    		(*it).m_score = average;   //将最后的得分赋值给每个选手
    	}
    
    
    }
    
    bool mycompar(Player& p1, Player& p2) //从小到到
    { 
    	return p1.m_score < p2.m_score;
    
    }
    
    
    //排序
    void SortPlayer(vector<Player>& player)
    { 
    	sort(player.begin(), player.end(), mycompar);
    }
    
    
    
    
    void print(vector<Player>& player)
    { 
    	for (vector<Player>::iterator it = player.begin(); it != player.end(); it++)
    	{ 
    		cout << "Name:" << (*it).m_name << " " << "Scores:" << (*it).m_score << endl;
    	}
    }
    
    int main()
    { 
    	vector<Player> player;
    	SetPlayer(player);
    	SetScore(player);
    	SortPlayer(player);
    	print(player);
        return 0;
    }

结果：  
直接运行就行，所有打分都是随机生成的
