c语言实现通讯录管理系统（c课程设计）

工具：Visual C++6.0

说明：

本系统基于C语言实现班级通讯录管理系统，为大一时学习C语言刚入门所做的课程设计。功能包括增、删、查、改等，非常适合初学者练手。通讯录包括的个人信息有姓名、学号、性别、籍贯、政治面貌、手机号、QQ号、宿舍等。主要用到了指针、结构体、遍历链表、文件读取等知识点。

运行效果：

代码：

 #include<stdio.h>
 #include<string.h>
 #include<stdlib.h>
 #include<windows.h>

     char name[];    //姓名

     char sex[];     //性别
     char from[];    //籍贯
     char political[];    //政治面貌
     char phone[];      //手机号
     char QQ[];         //QQ号
     char dorm[];     //宿舍
     struct student *next;  //结构体指针
 }stu;
