❸ 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;

};
//函數聲明
typedef struct contaxt CONT;

CONT *AddContaxt(int n);
CONT *FindCon(CONT *head);

❺ C語言程序設計，通訊錄管理系統
/*【用C語言編寫具有數據插入、修改、刪除、顯示和查詢功能的電話薄管理程序】
1、數據包括：人名、工作單位、電話號碼和E-mail地址。
2、可對記錄中的姓名和電話號碼進行修改。
3、可增加或刪除記錄。
4、可顯示所有保存的記錄。
5、可按人名或電話號碼進行查詢。
另：採用結構體數組和文件系統實現。結構體包括人名、工作單位、電話號碼和E-mail
絕對原創，2010年7月12日晚剛寫完測試通過的，純C語言！ */
