C語言如何實(shí)現(xiàn)會(huì)員管理系統(tǒng)

本文小編為大家詳細(xì)介紹“C語言如何實(shí)現(xiàn)會(huì)員管理系統(tǒng)”，內(nèi)容詳細(xì)，步驟清晰，細(xì)節(jié)處理妥當(dāng)，希望這篇“C語言如何實(shí)現(xiàn)會(huì)員管理系統(tǒng)”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(xué)習(xí)新知識(shí)吧。

會(huì)員信息包括：會(huì)員號(hào)（6位數(shù)，唯一），姓名，身份證號(hào)，聯(lián)系電話，狀態(tài)（1表示正常，0表示掛失）。

會(huì)員管理包括：會(huì)員的添加、刪除、修改（會(huì)員號(hào)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(jié)構(gòu)體，存儲(chǔ)會(huì)員賬號(hào)、姓名、身份證號(hào)、聯(lián)系方式、狀態(tài)、余額 
{
    long no;
    char name[20];    //姓名、身份證號(hào)含有字符，使用char定義 
    char IDcard[19];
