2. c语言课程设计：医院挂号收费管理系统
三点注意一下应该没有问题了
1结构的构造
2文件的读入和操作
3文件输出
算法的部分不难
lz好好翻翻书，静下心来，挺简单的其实
像这种问题在网络上面，一般的人都不太乐意回答
就算回答了，也是不痛不痒的，就像我一样
除非有人正好做过这道题~~
哈哈

在楼上的这位基础上稍候修改了一下,因为其在TC中不能正常编译.......
4. 用C语言做一个医院信息管理系统（HIS）
医生系统具有系统结构紧凑，效率高，实用性好，有很高的可靠性与稳定性。系统操作简便，系统提供优化的系统录入界面，可以大幅度提高输入信息的速度及准确性.
5. 求教大神：C语言课程设计报告——医院挂号系统
我给你讲下思路吧，如果实在不能自己搞定 我再帮你
1、录入功能 核心函数就用scanf 再配合循环
2、添加 这和录入差不多 只是添加的位置在最后
3、删除 可以用一条其他信息覆盖要被删掉的信息
5、修改 先用顺序查找找到要被修改的信息 然后录入要修改的部分数据
6、浏览 依次输出所有信息即可
7、编号查询 输入编号 然后顺序查找 输出 ok
8、排序 用冒泡法
6. 用c语言编写医院排队看病系统，急啊！！！求大神！！

break;
}

}
}
}
void main()
{
SeeDoctor();
}
病人的姓名等信息就在结构体里加几个成员就行了！主要功能已经实现了！
我截张图给你吧！
