C語言學習之用鏈表實現通訊錄

本程序主要功能是對聯系人信息進行，添加、刪除、查找、插入、顯示功能

說明：調用的鏈表操作接口請參考：http://www.linuxidc.com/Linux/2015-02/113142.htm

這裡面有我實現的鏈表操作的接口的詳細實現過程，並進行過測試的哦！！！

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "addressBookList.h"

/* 顯示鏈表所有信息*/

return;
}

/*添加聯系人*/
chainListType *add_contact(chainListType *head)
{
DATATYPE_T contactInfo;

printf("please input contact information\n");
scanf("%s %s %s",contactInfo.key,contactInfo.add,contactInfo.telephone);

/*按照關鍵字查找聯系人*/
