c语言电话簿管理系统
㈠ 求用C语言编写一个 通讯录管理系统 。设计要求如下
这个主要用到链表来做就可以的啦，链表的基本操作（创建、插入、删除等）要掌握好。之前我自己写有一个，和你的功能差不多，但是变量有所不同，给你参考参考吧，可以仿照。不懂的再问吧。代码如下：
#include"stdafx.h"
using namespace std;
//结构体
struct contaxt
{
char name[10];
char sex[5];
char Adrre[50];
char Class[20];
char Mobi[20];
char qq[10];
struct contaxt *next;
};
//函数声明
typedef struct contaxt CONT;
CONT *InsertCon(CONT *head);
CONT *AddContaxt(int n);
CONT *FindCon(CONT *head);
CONT *AmendMessage(CONT *head);
CONT *DeleteMessage(CONT *head);
void showmessage(CONT *head);
int menu(CONT *head);
CONT *saveFileCONT(CONT *head );
CONT *readFileCONT(CONT *head);
int choose;
//入口
void main()
{
//system("color F4");
CONT *head;
head = NULL;
menu(head);
}
//系统主菜单
int menu(CONT *head)

㈣ C语言程序设计，通讯录管理系统
/*【用C语言编写具有数据插入、修改、删除、显示和查询功能的电话薄管理程序】
1、数据包括：人名、工作单位、电话号码和E-mail地址。
2、可对记录中的姓名和电话号码进行修改。
3、可增加或删除记录。
4、可显示所有保存的记录。
5、可按人名或电话号码进行查询。
另：采用结构体数组和文件系统实现。结构体包括人名、工作单位、电话号码和E-mail
