3. 求用C語言編寫一個 通訊錄管理系統 。設計要求如下

這個主要用到鏈表來做就可以的啦，鏈表的基本操作（創建、插入、刪除等）要掌握好。之前我自己寫有一個，和你的功能差不多，但是變數有所不同，給你參考參考吧，可以仿照。不懂的再問吧。代碼如下：

#include"stdafx.h"
using namespace std;
//結構體
struct contaxt
{
char name[10];
char sex[5];
char Adrre[50];
char Class[20];

char qq[10];
struct contaxt *next;
};
//函數聲明
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()

}
