用C++编写一个学生通讯录管理系统

Question

其实这是我的数据结构之c++语言描述的作业。
问题描述：
实现学生通讯录管理的几个操作功能（新建，插入，删除、从文件读取、学如文件和查询、屏幕输出）。通讯录中学生的信息由有学号、姓名、出生日期、性别、电话和地址）。要求利用链式存储结构来实现。程序中要有一些文字注释（因为这个是作业，注重编写过程）。
其中。系统的菜单要如下：
1、新建学生通讯录
2、向学生通讯录插入学生信息
3、在通讯录删除学生信息
4、从文件中读取通讯录信息
5、向文件写入学生通讯录信息
6、在通讯录中查询学生信息
7、在屏幕中输入全部学生信息。
8、退出
用vc。因为在学c++嘛。又不是只为编写一个简单程序。控制台程序就行，不必可视界面啊。还有，不要出现c的命令，用c++来解决。（因为是学习，学C++）

这个是我以前写的程序，本来有个已经写好的文档，里面存了一些虚拟的联系方式，如果需要，我把整个工程也发给你，留个邮箱....O(∩_∩)O~

Answer 2

私下找我，我发给你。我的那个很容易懂的，而且全是c++语言描述本回答被提问者采纳

Answer 3

看你急不急，等几天我也要开始写毕业论文了，如果不急等我写好了传上来吧，当然，我不确定我什么时候能写好。但是我想一定没有人愿意为了100分去专门写这个吧。当然，我也不是想要你分。因为我也不确定我什么时候能写好。
所以，最好还是去下载吧

Answer 5

你一定要用VC吗？其实VB编界面要简单地多
