C語言如何實現會員管理系統

本文小編為大家詳細介紹“C語言如何實現會員管理系統”，內容詳細，步驟清晰，細節處理妥當，希望這篇“C語言如何實現會員管理系統”文章能幫助大家解決疑惑，下面跟著小編的思路慢慢深入，一起來學習新知識吧。

會員信息包括：會員號（6位數，唯一），姓名，身份證號，聯系電話，狀態（1表示正常，0表示掛失）。

會員管理包括：會員的添加、刪除、修改（會員號不能修改）、掛失、查詢、接觸掛失。

先給大家看看效果：

上代碼：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct VIP             //定義結構體，存儲會員賬號、姓名、身份證號、聯系方式、狀態、余額 
{
    long no;
    char name[20];    //姓名、身份證號含有字符，使用char定義 
    char IDcard[19];
    char phone[12];   //聯系電話有11位，超出了int的范圍，使用字符串定義 
    int zhuangtai;      //如果狀態為1，則正常，若為0，則狀態為掛失 
    int yue;
};
struct VIP s[50];     //定義結構體數組 
int n=0;              //n表示存入的會員數量 
 
void init();          //含義見main主函數 
void print();
