//功能：实现裁判打分<br /> //描述:为那些初学者学习方便所写的<br /> //程序要求如下:<br /> /************************<br /> 模拟一个裁判给比赛选手打分。<br /> 1．要求如下：<br /> ⑴ 裁判人数为UMPIRE；<br /> ⑵ 参赛选手为任意人；<br /> ⑶ 裁判给选手打分；<br /> ⑷ 去掉一个最高分，一个最低分，取其平均分为选手得分；<br /> ⑸ 按参赛选手的序号显示选手得分；<br /> ⑹ 按名次显示参赛选手得分（用插入法排序）。<br /> 2．提示：<br /> ⑴ 定义一个类名为Result的记分类为选手记分，数据成员至少包括选手编号（用整型）、姓名（用字符数组）、裁判为选手的打分及得分（用实型数组）等，成员函数自定（必须有构造函数），将类的定义保存在“result.h”中；<br /> ⑵ 测试程序（保存在exp_206.cpp中）采用交互方式：<br /> ① 提示输入参赛选手人数；<br /> ② 提示输入所有参赛选手的编号及姓名；<br /> ③ 显示比赛开始，请为选手打分；<br /> ④ 显示：去掉的最高分、最低分，选手得分；<br /> ⑤ 比赛结束，按编号显示选手的得分；<br /> ⑥ 按名次显示选手得分。<br /> **************************************/<br /> #include <iostream><br /> #include <string><br /> #include <algorithm><br /> using namespace std;<br /> const int UMPIRE=5;<br /> class Result{<br /> public:<br /> Result(int n,char *p)//编号,姓名<br /> {<br /> if(strlen(p)<=0)<br /> cout << " error" << endl;<br /> num=n;<br /> strcpy(name,p);<br /> score=0;<br /> memset(judgescore,0,UMPIRE);<br /> }<br /> Result()<br /> {<br /> num=0;<br /> name[0]='/0';<br /> score=0;<br /> memset(judgescore,0,UMPIRE);<br /> }<br /> Result(const Result& rhs)<br /> {<br /> num=rhs.num;<br /> strcpy(name,rhs.name);<br /> score=rhs.score;<br /> memcpy(judgescore,rhs.judgescore,UMPIRE);<br /> }<br /> void InitResult(int n,char *p)<br /> {<br /> if(strlen(p)<=0)<br /> cout << " error" << endl;<br /> num=n;<br /> strcpy(name,p);</p> <p> score=0;<br /> memset(judgescore,0,UMPIRE);<br /> }<br /> void SetJudgeScore(int *s)<br /> {<br /> int ix=0;<br /> while(ix<UMPIRE)<br /> {<br /> judgescore[ix]=s[ix];<br /> ix++;<br /> }<br /> }</p> <p> int* GetJudgeScore()<br /> {<br /> return judgescore;<br /> }<br /> int GetScore()<br /> {<br /> return score;<br /> }<br /> int GetNumber()<br /> {<br /> return num;<br /> }<br /> void ShowName()<br /> {<br /> cout << name;<br /> }<br /> int FindHighPos();<br /> int FindLessPos();<br /> int FindHigh()<br /> {<br /> return judgescore[FindHighPos()];<br /> }<br /> int FindLess()<br /> {<br /> return judgescore[FindLessPos()];<br /> }<br /> void DoCalculatorScore();</p> <p> friend ostream& operator<<(ostream &out,Result );<br /> ~Result(){}<br /> private:<br /> int num;
