    题目描述

    注：本题目自由设计，但必须使用类进行代码设计。

    世界杯32支参赛队分为八个小组,每个小组分别有四支球队进行比赛，每支球队都必须和其他三支球队进行且只进行一场比赛,每组4个队循环比赛，共打6场(a1-a2;a1-a3;a1-a4;a2-a3;a2-a4;a3-a4),每场比赛90分钟，胜平负分别积3、1、0分。每个小组积分的前两名球队出线进入淘汰赛阶段的1/8决赛，共16支队，即“16强”。

    每个小组分别有四只球队，其排名按以下规则确定：
    a、积分高者排名靠前
    b、小组中总净胜球高者排名靠前
    c、小组中总进球数高者排名靠前
    d、不能确定
    净胜球数是指进球数（正数）与失球数（正数）的差。
    如，红队胜黄队4：2，蓝队胜黄队3：1，红队负蓝队2：3
    红队进6球，失5球，净胜球数为：6-5=1
    黄队进3球，失7球，净胜球数为：3-7=-4
    蓝队进6球，失3球，净胜球数为：6-3=3
    //以下是可供参考的代码
    #include <stdio.h>
    #include <iostream>
    #include <string>
    using namespace std;

    class FootballGroup
    {
    private:
        int score[4]; //总积分
        int goaldiff[4]; //总净胜球
        int totalgoals[4]; //总进球数
        string teamname[4] ; //球队的名称
    public:
        FootballGroup()
        {
            for(int i=0; i<4; i++)
            {
                score[i]=goaldiff[i]=totalgoals[i]=0;
            }
        }
        void setTeamName(int teamindex,string name)  //设置第teamindex+1个队的队名
        {
            teamname[teamindex] = name;
        }
        void addMatchresult(int teamindex1,int teamindex2,int score1,int score2);
        void showResult();
    };
    int main()
    {
        FootballGroup GroupA;
        string name;
        int i,j;
        for(i=0; i<4; i++)
        {
            cin>>name;
            GroupA.setTeamName(i,name); //球队a1,a2,a3,a4的名称
        }
        int score1,score2;
        for(i=0; i<3; i++) //a1-a2;a1-a3;a1-a4;a2-a3;a2-a4;a3-a4
            for(j=i+1; j<4; j++)
            {
                cin>>score1>>score2; //两队的比分
                GroupA.addMatchresult(i,j,score1,score2);
            }
        GroupA.showResult();
        return 0;
    }

    输入

    第一行 4个参赛队伍的名称
    第二行开始到第七行，6场比赛的比分(a1-a2;a1-a3;a1-a4;a2-a3;a2-a4;a3-a4)

    输出

    进入淘汰赛阶段的两只球队，如果不能确定，则输出"NO"

    样例输入

    a1 a2 a3 a4
1 2
0 0
2 3
3 1
2 2
1 2

    样例输出

    a2 a4
