题目描述

注:本题目*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
