C语言如何实现会员管理系统

本文小编为大家详细介绍“C语言如何实现会员管理系统”，内容详细，步骤清晰，细节处理妥当，希望这篇“C语言如何实现会员管理系统”文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。

会员信息包括：会员号（6位数，唯一），姓名，身份证号，联系电话，状态（1表示正常，0表示挂失）。

会员管理包括：会员的添加、删除、修改（会员号不能修改）、挂失、查询、接触挂失。

先给大家看看效果：

上代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct VIP             //定义结构体，存储会员账号、姓名、身份证号、联系方式、状态、余额 
{
    long no;
    char name[20];    //姓名、身份证号含有字符，使用char定义 
    char IDcard[19];
    char phone[12];   //联系电话有11位，超出了int的范围，使用字符串定义 
    int zhuangtai;      //如果状态为1，则正常，若为0，则状态为挂失 
    int yue;
};
struct VIP s[50];     //定义结构体数组 
int n=0;              //n表示存入的会员数量 
 
void init();          //含义见main主函数 
void print();           
struct VIP gete();
void add1();             
void findbyno();
