使用C语言打造通讯录管理系统和教学安排系统的代码示例

使用C语言打造通讯录管理系统和教学安排系统的代码示例这篇文章主要介绍了使用C语言打造通讯录管理系统和教学安排系统的代码示例,利用C语言强大的数组和指针能够更加清晰地体现设计思路，需要的朋友可以参考下：通讯录管理系统实现了通讯录的录入信息、保存信息、插入、删除、排序、查找、单个显示等功能。

完整的代码如下：#include <stdio.h>#include <malloc.h> //得到指向大小为Size的内存区域的首字节的指针//#include <string.h>#include <stdlib.h> //标准库函数//#define NULL 0#define LEN sizeof(struct address_list) //计算字节//int n;struct address_list{char name[30];

C语言课程设计——通讯录软件源代码(完美版)

C语言课程设计——通讯录软件源代码(完美版)

C语言课程设计——通讯录软件源代码（完美版）通讯录完美版操作说明书编译环境:Visual C++ 6.0初始密码为:111111主菜单:选择编号进行相应的操作:选择“1”:输入编号:如“001”。

通讯录数据结构如下，只要输入的数据不超过允许的范围即可:struct callmember //定义数据结构{char code[8]; // 编号char name[20]; // 姓名char callnumber[16]; // 电话号码char address[30]; // 地址};输入完后“Enter”结束。

然后又回到“main menu”。

选择“2”显示通讯录信息，但此时刚输入的信息还没保存，选择“3”就可以将联系人信息保存在“通讯录.txt”文件中了，这个文件是自动生成的不需自己建立。

除此外还有查询、修改、删除功能。

当然功能有限，望有能之士加以修改，完善内容～本软件是一个值得收藏的软件，可以用于管理自己的通讯录～源程序:/***************************C语言课程设计*****************************//******************************************************************* **//******************************************************************* **//******************************************************************* **//***** 项目名称: 通讯录管理系统 *****/ /***** 作者: *****/ /*****专业: ***** *****/ /***** 班级: ***** *****/ /***** 学号: ********* *****//***** 指导老师: *****/ /***** 完成时间: 2010.7.12 *****/ /***** 联系电话: 150*******3 *****/ /***** 初始密码: 111111 *****//*********************************************************************/ /******************************************************************* **//******************************************************************* **//************************预处理***************************************/ #include<string.h> #include<stdio.h>#include<stdlib.h>#include<windows.h>#include<conio.h>#define N 301 //修改N的值，就可以改变记录个数，实际容纳人数为N-1 struct callmember //定义数据结构{char code[8];
