请好心的师傅帮帮忙,急求一个运动会的C++程序,每个模块要有详细的注释,我的分全给你了

Question

要求:运动会分数统计
【问题描述】：参加运动会的n个学校编号为1~n。比赛分成m个男子项目和w个女子项目，项目编号内分别为1~m和m+1~m+w。由于各项目参加人数差别较大，有些项目取前五名，得分顺序为7，5，3，2，1；还有些项目只取前三名，得分顺序为5，3，2。写一个统计程序产生各种成绩单和得分报表。
【基本要求】：产生各学校的成绩单，内容包括各校所取得的各项成绩的项目号、名次（成绩）、姓名和得分；产生团体总分报表，内容包括校号、男子团体总分、女子团体总分和团体总分。
师傅,头文件有错呀 ....怎么修改一下,还有能不能解释一下模块,我是个笨蛋,师傅帮帮吗,好吗?

Answer 1

现在可以了， 你再试试吧

/*学校运动会管理系统
问题描述：
(1) 初始化输入:N-参赛院系总数，M-男子竞赛项目数，W-女子竞赛项目数；
(2) 各项目名次取法有如下几种：
取前5名：第1名得分 7，第2名得分 5，第3名得分3，第4名得分2，第5名得分 1；
(3) 由程序提醒用户填写比赛结果，输入各项目获奖运动员的信息。
(4) 所有信息记录完毕后，用户可以查询各个院系或个人的比赛成绩，生成团体总分报表，查看参赛院系信息、获奖运动员、比赛项目信息等。
(5) 原始数据需保存到磁盘文件中。
