一、需求分析

题目：超市会员管理系统

要求：从分析题目的需求入手，按设计抽象数据类型、设计算法、通过设计实现抽象数据类型、编制上机程序和上机调试等若干步骤完成题目，最终写出完整的分析报告。前期准备工作完备与否直接影响到后序上机调试工作的效率。在程序设计阶段应尽量利用已有的标准函数，加大代码的重用率。

二、问题描述

【问题描述】
超市会员管理基本业务活动包括:对一个会员基本信息的输入、输出、查询、删除、插入等等。试设计一个超市会员管理系统，将上述业务活动借助于计算机系统完成。
【基本要求】：要输出相应界面：链式存储方法实现。
〈1〉每个会员的信息包括：姓名、身份证号、电话、会员等级、优惠政策
〈2〉系统应实现的操作及其功能定义如下:

1.输入：

2. 查找：
3. 插入：
4.删除：
5.显示：

}

（2）文件管理

void read(VIPList *L) {//打开文件流FILE *fp = fopen("数据", "w");if (fp == NULL) {printf("文件打开失败\n");exit(EXIT_FAILURE);}//读取第一行的会员节点总数fscanf(fp, "%d", &L->count);//循环读取数据，循环次数为countfor (int i = 1; i <= L->count; i++) {//创建新节点VIPNode *s = (VIPNode *)malloc(sizeof(VIPNode));//读取数据fscanf(fp, "%s ", s->VIP.no);fscanf(fp, "%s ", s->VIP.name);fscanf(fp, "%s ", s->VIP.ID);fscanf(fp, "%s ", s->VIP.phone);fscanf(fp, "%d ", &s->VIP.money);fscanf(fp, "%s ", s->VIP.grade);fscanf(fp, "%s ", s->VIP.discounts);//将新节点插进链表尾部（尾插法）s->next = NULL;L->tail->next = s;L->tail = s;}//关闭文件流fclose(fp);
}

（3）会员等级

void counts(VIPNode *q){char grade[6][50]={"普通","白银","黄金","铂金","钻石","黑金"};//>=0,普通；>=500,白银；>=1000,黄金；>=3000,铂金；>=6000，钻石；>=10000,黑金 	char discounts[6][50]={"原价","九折","八八折","八五折","八折","七折"};int num;num=q->VIP.money/100; if(num<=5) { strcpy(q->VIP.grade,grade[0]);strcpy(q->VIP.discounts,discounts[0]); }else if(num<=10){ strcpy(q->VIP.grade,grade[1]);strcpy(q->VIP.discounts,discounts[1]);}else if(num<=30){ strcpy(q->VIP.grade,grade[2]);strcpy(q->VIP.discounts,discounts[2]);}else if(num<=60){ strcpy(q->VIP.grade,grade[3]);strcpy(q->VIP.discounts,discounts[3]);}else if(num<=100){ strcpy(q->VIP.grade,grade[4]);strcpy(q->VIP.discounts,discounts[4]);}else{ strcpy(q->VIP.grade,grade[5]);strcpy(q->VIP.discounts,discounts[5]);} 
}

（4）排序函数

void sort(VIPList *L) {printf("会员个数为%d：",L->count); //插入排序VIPNode *p, *pre, *tmp;//p指向第二个会员节点p = L->head->next;//链表从头节点和第一个会员节点处断开L->head->next = NULL;//从第一个会员节点开始一直往后循环while (p) {//存好下一个节点的指针tmp = p->next;//找到插入位置pre = L->head;while (pre->next != NULL && strcmp(pre->next->VIP.no,p->VIP.no)<0){ pre = pre->next;} //更新尾指针if (pre->next == NULL) {L->tail = p;}//插入p->next = pre->next;pre->next = p;//跳到下一个p = tmp;}printf("链表排序完成！\n");system("pause");
