一、比赛规则
- 学校举行一场演讲比塞，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。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。
- 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个选手，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。
二、比赛功能
- 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一个阶段
- 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 - 清空比赛记录：将文件中数据清空
- 退出比赛程序：可以退出当前程序
[ 注意 ]：csv格式可以用excel或记事本方式打开。
