标签：c语言结构体通讯录

-------------------------------------------------------------------------------------------------------

本通讯录实现了一个普通通讯录的所有功能；包括：联系人的添加，删除，修改，排序，以及清空等功能；采用结构体自定义类型实现；排序部分采用的是冒泡排序。界面比较友好，希望各位朋友批评指正。

C语言代码：

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

# define MAX 1000          //可存放最大联系人的数量

     _revise_contacts,        //4——>修改联系人
     _show_contacts,          //5——>显示联系人
     _sort_contacts,          //6——>排序联系人
     _empty_contacts          //7——>清空联系人
