求c语言写的"一个简单的学生成绩管理程序"(等待)

[xfary]

利用数组，设计一个简单的学生成绩管理程序。
要求：
1、一个学生的信息包括：序号、学号、性别、成绩1、成绩2、成绩3；
2、在main函数中设计并利用字符菜单进行管理项目的选择，程序一次运行可根据选择完成一项或多项操作，通过选择菜单的退出(或结束)项来结束程序的运行。
3、管理功能包括列表显示成绩清单、求平均成绩、查找最高分。各项功能分别用自定义函数实现；
4、其中列表显示需要根据进一步的会话选择，可以列出全部数据、按指定的性别筛选列表(性别可用0、1编码)、按指定学号列出个人全部数据、按平均成绩排序列表；
5、求平均成绩需要根据进一步的会话选择，可以按个人或按科目进行；
6、查找需要根据进一步的会话选择，可按最高个人平均分进行，可按指定科目的最高分进行，可按各科均≥80分进行。查找后列出满足条件者的全部信息；
7、为了便于调试，原始数据用赋初值的方法存入数组。

[xfary]

或者:
编写程序，设计一个电话簿管理程序。
(要求：
1、每条数据包括：姓名、班级、电话号码、E-mail地址；
2、在main函数中设计并利用字符菜单进行管理项目的选择，程序一次运行可根据选择完成一项或多项操作，通过选择菜单的退出(或结束)项来结束程序的运行。
3、管理功能包括：加入一条新的电话记录、删除一条电话记录、显示保存的所有电话记录、修改某条记录、查询、排序显示；
4、查询功能包括：按人名查询电话号码、按电话号码查询人名（如宿舍电话一个号码对应多人）；
5、排序显示功能包括：按照电话号码排序显示、按照姓名字母排序显示，并且当一页显示不下时可分页显示；
6、数据结构采用结构体，数据存储采用文本文件。

如果电话簿管理程序在电脑上运行，是作业
写嵌入式的程序的话，有意思！

[xfary]

求的就是作业,偶现在是搞C# windows应用程序的,有些时间不用c和c++了,朋友让帮他用c写份简单的作业,竟然写不出来,惭愧呀,只有在这里求救啦!
