运行环境
Windows 11，codeblocks

项目分析
该会员管理系统用于管理会员信息，功能全面，包括会员登记、信息修改、续费、消费结算、退卡、挂失以及统计。系统通过结构体数组存储会员信息，使用文件操作将会员信息保存到磁盘，确保程序退出后数据不会丢失。

但是这个代码未充分利用结构体中的next指针，链表结构未被使用。

升级开发
将数组改为链表，可以提高灵活性，避免内存浪费。

点击查看代码

struct employee {
    int num;
    char name[10];
    char sex[10];
    int age;
    char xueli[30];
    int wage;
    int xiao;
    int yu;
    char addr[30];
    long tel;
    struct employee* next;
};

struct employee* head = NULL;

点击查看代码

void input() {
    struct employee* new_emp = (struct employee*)malloc(sizeof(struct employee));
    printf("卡号: ");
    scanf("%d", &new_emp->num);
    printf("请输入姓名: ");
    scanf("%s", new_emp->name);
    printf("请输入性别: ");
    scanf("%s", new_emp->sex);
    printf("请输入年龄: ");
    scanf("%d", &new_emp->age);
    printf("请输入学历: ");
    scanf("%s", new_emp->xueli);
    printf("请输入缴费金额: ");
    scanf("%d", &new_emp->wage);
    printf("请输入电话: ");
    scanf("%ld", &new_emp->tel);
    new_emp->yu = new_emp->wage;
    new_emp->next = head;
    head = new_emp;
    save();
    printf("\n创建完毕!\n");
}

考虑了客户需求，我增加了会员积分系统，根据消费金额给予积分，积分可以用于抵扣消费或兑换礼品。

点击查看代码

void add_points(struct employee* emp, int amount) {
    emp->points += amount / 10; // 每消费10元增加1积分
}

void use_points(struct employee* emp, int amount) {
    if (emp->points >= amount) {
        emp->points -= amount;
        emp->xiao -= amount; 
    } else {
        printf("积分不足，无法抵扣。\n");
    }
}

总结
通过逆向分析现有的会员管理系统，我学习了逐步拆解其内部逻辑和数据结构。这一过程不仅锻炼了我的逻辑思维能力，也让我对软件架构有了更深入的理解。
在开发新的会员管理系统时，我结合逆向分析的结果，通过链表优化了系统的性能，并增加了新的功能以满足用户需求，其中我重新回顾了链表的各种知识。这一过程让我深刻体会到了需求分析的重要性，只有准确理解用户需求，才能开发出真正符合用户期望的系统。
总的来说，这次逆向软件设计和开发的经历让我受益匪浅。我不仅提升了自身的技术能力，也对软件开发过程有了更全面、更深入的认识。
