演讲比赛流程管理系统
比赛规则:
- 学校举行一场演讲比赛,共有12人参加比赛,比赛共两轮,第一轮位淘汰赛,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,整天按照选手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,淘汰组内名最后的三位选手,前三名晋级,进入下一轮比赛
- 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
程序功能:
- 开始演讲比赛:完成整届比赛的流程每场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:查看之前表三前三名结果,没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
