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:

三、总体设计

四、详细设计

1)数据类型

typedef struct
{
	char no[10];//账号 
	char name[10];//姓名 
	char ID[30];//身份证号 
	char phone[16];//电话 
	int money;	//金额 
	char grade[10];//等级 
	char discounts[10]; //折扣 
}VIP;   //单个会员信息 
 
typedef struct node{
    VIP VIP;            //数据域 
    struct node *next;   //指针域 
}VIPNode;   //会员节点 

typedef struct{
    VIPNode *head;  //头指针 
    VIPNode *tail;  //尾指针 
    int count;
}VIPList;     // 会员链表 

2) 函数名

void counts(VIPNode *q);//会员等级 
int menu();   //菜单 
void Instruction();//系统说明 
void initialize(VIPList *L);//初始化链表 
void read(VIPList *L);//从文件中读取 
void input(VIPList *List,int m);  //输入

7)其他模块

(1)初始化

void initialize(VIPList *L) { //初始化 
	//创建头节点
	VIPNode *s = (VIPNode *)malloc(sizeof(VIPNode));
	s->next = NULL;
	//初始化链表:
	//头尾指针均指向头节点,初始长度为零
	L->head = s;
	L->tail = s;
	L->count = 0;
}

 (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count
	for (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");
}

 五、调试与测试

 1)运行登陆模块,如图所示。

输入正确的用户名和密码登陆

用户名:000

密码:123

 2)登陆成功后进入主菜单

 3)输入

按1进入会员信息建立模块,输入会员的个数,根据个数输入会员的账号1111,姓名zxc,身份证号123456789123456789,联系电话12345678912,消费金额5000;账号2222,姓名asd,身份证号789456123789456123,联系电话78945612378,消费金额8600,会员等级和优惠政策根据消费金额显示出来,如图所示。

 4)显示

按2进入会员信息显示模块,信息通过排序后输出

 5)查询

按4进入查询会员信息界面

按子菜单1进行账号查询,输入账号2222查询会员信息

按子菜单2进行姓名查询,输入姓名zxc查询会员信息

 6)插入

按4进入插入会员信息界面

输入会员账号5555,姓名qwe,身份证号456789123456789123,联系电话45678912345,消费金额6000,根据消费金额显示会员等级和优惠政策,会员信息插入到链表中

 

 7)修改

按5进入修改会员信息界面

输入要修改的会员的账号,按1修改姓名为vbn,按2修改身份证号为987654321987654321

 8)删除

按6进入删除会员信息,输入要删除的会员账号进行删除

 9)充值或消费

 按8进行会员消费或充值

输入账号5555,选择消费类型,输入金额

总结


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,通过链表进行会员信息的增删改查。
