更新時間：2020年05月25日 08:54:57 作者：hackbuteer1
這篇文章主要為大家詳細(xì)介紹了C語言通訊錄管理系統(tǒng)的完整版本，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價值，感興趣的小伙伴們可以參考一下
C語言實現(xiàn)了通訊錄的錄入信息、保存信息、插入、刪除、排序、查找、單個顯示等功能。。
完整的代碼如下：
#include <stdio.h> 
#include <malloc.h> //得到指向大小為Size的內(nèi)存區(qū)域的首字節(jié)的指針// 
#include <string.h> 
#include <stdlib.h> //標(biāo)準(zhǔn)庫函數(shù)// 
#define NULL 0 
#define LEN sizeof(struct address_list) //計算字節(jié)// 
int n; 
struct address_list 
{ 
 char name[30]; //名字 
 char work[30]; //職業(yè) 
 char handset[30]; //手機(jī)

 char address[30]; //通訊地址 
 struct address_list *next; 
}; 
struct address_list *shifang(struct address_list *head); // 釋放內(nèi)存函數(shù)聲明 
//創(chuàng)建函數(shù)，不帶頭結(jié)點的鏈表
