演讲比赛系统
1.需求分析
- 学校举行一场比赛，共有12人参加。比赛共两轮，第一轮为淘汰赛，第二轮为决赛。
- 每名选手都有对应的编号：如10001~10012。
- 比赛方式：分组比赛，每组6个人。
- 第一轮分为两个小组，整体按照选手的编号进行抽签后顺序演讲。
- 十个评委分别给每名选手打分，去除最高分和最低分，求的平均分为本轮选手的成绩。
- 当小组演讲完后，淘汰组内排名最后的三名选手，前三名晋级，进入下一轮的比赛。
- 第二轮为决赛，前三名胜出。
- 每轮比赛过后需要显示晋级选手的信息。
2.程序和功能
3.程序逻辑
3.1建立演讲比赛管理类
void SaveRecord(); //初始化 void InitSpeech(); //判断文件是否为空 bool File_Is_Empty; //往届数据的容器 map<int, vector<string>>M_Record; ~Speech_Manager(); void CreatSpeaker(); string CreatName(int a); void ShowScore(); void Wait_Revolution(); //往届记录 void ShowRecord(); //清空记录 void ClearRecord(); //读取记录 void LoadRecod(); //创建轮数 int Revolution; //第一轮比赛人员编号 vector<int>v1; //第二轮比赛人数编号 vector<int>v2; //获胜人编号 vector<int>vVictory; //存放编号和对应具体选手的容器 map<int, Speaker>M_Speker; //存放届数 };
3.2开始演讲比赛程序
比赛流程分析：
抽签—>开始第一轮演讲比赛—>显示第一轮比赛结果—>抽签—>开始第二论比赛—>
显示前三名结果—>保存分数。

string NA2[] = { "伟", "刚", "勇", "毅", "俊", "峰","秀", "娟", "英", "华", "慧" };
srand((unsigned int)(time)(NULL));
for (int i = 0; i < a; i++)
