12 比赛规则
13 学校举行一场演讲比赛，共有12个人参加。比赛共两轮，第一轮为淘汰赛，第二轮为决赛。
14 比赛方式：分组比赛，每组6个人；选手每次要随机分组，进行比赛
15 每名选手都有对应的编号，如 10001 ~ 10012
16 第一轮分为两个小组，每组6个人。 整体按照选手编号进行抽签后顺序演讲。
17 当小组演讲完后，淘汰组内排名最后的三个选手，前三名晋级，进入下一轮的比赛。
18 第二轮为决赛，前三名胜出
19 每轮比赛过后需要显示晋级选手的信息
20 程序功能
21 开始演讲比赛：完成整届比赛的流程，每个比赛阶段需要给用户一个提示，用户按任意键后继续下
22 一个阶段
23 查看往届记录：查看之前比赛前三名结果，每次比赛都会记录到文件中，文件用.csv后缀名保存
24 清空比赛记录：将文件中数据清空
25 退出比赛程序：可以退出当前程序
