Think:
文件的输入输出那一块儿 还是不怎么会~~ 好像只成功输入输出了 user.dat那一份~~ 用了好久好久的时间写的程序~~, 感觉和上一篇blog的思路基本相同就是 各种调用函数。。。

以台桌模块为例：
整体框架如下：
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include<windows.h>
#include<conio.h>
#include<bits/stdc++.h>
using namespace std;

struct node
{
char name[50]; //订单号
char num[50]; //桌号
char status[50];//订单状态
char action[50];//活动
char payoff[50];//付款状态
double price;//金额
int dish_num;//菜号
int typ; //菜品名字
struct node *next;
}*tab, *dish, *user, *order;
/*台桌界面*/
void add_table();//增加台桌
void delete_table();//删去台桌
void alter_table();
