C语言学习之用链表实现通讯录

本程序主要功能是对联系人信息进行，添加、删除、查找、插入、显示功能

说明：调用的链表操作接口请参考：http://blog.csdn.net/qlx846852708/article/details/43482497

这里面有我实现的链表操作的接口的详细实现过程，并进行过测试的哦！！！

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#include "addressBookList.h"

/* 显示链表所有信息*/

        phead = phead->next;

    }

    return;

}

/*添加联系人*/
