基于C++的餐饮预订系统-创新互联
前言
一、系统介绍
二、系统设计
一、系统介绍
一个餐饮预订系统。程序运行后,首先选择用户类型,然后从文本文件读入菜单信息
进行初始化,根据用户类型不同在控制台界面上提供不同功能选择。用户选择某项功能
后,根据提示进行操作;操作完成后,能返回功能选择菜单重新选择,直至用户退出。
客户功能:
1) 预订——打印出可选菜单,提示用户选择;在用户选择后,提示用户输入个人
信息,记录下信息,并保存至本地文件。
2) 查询/退订——显示所有的已订的订单列表,提示输入退订订单;用户输入后,
如果卖家尚未确认订单,则成功退订并修改本地文件;否则提示退订失败。
卖家功能:
1) 添加/删除菜单——菜单根据文件初始化后,卖家可以对其进行修改,包括添加
和删除菜式等,修改后将新菜单保存至文件,下次初始化仍可用。
2) 查询/修改订单——读取本地文件,显示所有的订单及其状态,提示确认订单或
不进行操作;卖家选择订单后,修改该订单为确认状态。
二.设计过程与讨论
1.设计思路
作为一个自助订餐系统,除了实现基本功能,还要能提供友好的用户界面,有良好的提示语句,做到不错的用户体验,并处理大部分的用户错误输入。
菜单:包含编号,菜名,价格。
订单:包含菜单,用户姓名,用户电话,用户地址,数量,订单日期,订单状态。
首先考虑买家功能。买家的类里存着姓名,地址,电话,点餐数量,订餐日期,以及所有该用户的订单。
预订:如果没有可选菜单,输出提示语句。否则,输出所有菜单。提示用户输入选择。若输入的菜单信息无效,则提示找不到菜单,请用户重新输入。若有效,测提示用户继续输入,或者用户选择下单结束。点完所有菜时,将所有用户刚点的菜打印出来,提示用户输入个人信息,包括姓名,电话,地址,以及订单的日期。完毕后,将订单保存到本地文件。然后返回上一层。
查询:若用户之前输入过姓名,则直接输出所有已下订单。否则,提示用户输入姓名,并根据姓名在订单里查找,然后输出,返回上一层。
退订:若该用户没有任何订单,则输出提示并返回上一层。否则,输出所有该用户已下订单的具体情况,并提示用户输入想要取消的订单,若错误输入,提示用户继续输入。否则判断该订单是否已确认,已确认则提示用户订单不可修改,否则输出提示语句,取消订单。然后将新的订单写入本地文件。
然后考虑卖家功能。
进入卖家菜单,需要输入密码。密码保存在本地文件,默认为888888。当用户输入正确密码,才可以进入系统。输入错误5次会自动退出。进入后,有5个功能供选择。
添加菜单。提示用户输入菜式编号,菜名,价格,可以继续添加,然后选择退出。程序加添加后的菜单保存至本地文件。
删除菜单。打印出所有菜单,提示用户输入编号,输入错误则提示无此菜式。否则提示菜式已删除。然后用户可以选择继续删除或返回上一层。
查询订单。若无订单,则提示没有订单。否则,输出所有订单的详细信息。
修改订单。若没有未确认的订单,则提示所有订单已确认。否则输出所有未确认的订单,并为每一个订单规定一个编号。用户可以选择一键确认或者逐一确认。一键确认则程序修改所有订单状态并保存至本地文件。逐一确认则由用户输入编号确认,最后在用户放回上一层的时候保存至本地文件。
修改密码。先由用户输入旧密码,正确之后提示输入新密码。新密码需输入两次,若两次都一样,则修改密码并保存至本地文件。
用户进入阶段。如果是点餐者,可以选择1;如果是卖家,可以选择2。
二、系统设计
1.1主函数头文件
#include#include#include#include#include#include "Menu.h"
#include "User.h"
//以上均为定义头文件
#pragma warning(disable : 4267)//VS2022版本,会出现C4267报错,防止其报错
using namespace std;
fstream finout;//文件读和写字节流
vectororder;//声明了一个Order数组order[]
vector
以下为主函数
int main()
{
string n;//定义一个字符串n,并初始化为空
bool success = 0;
cout<< setw(55)<< "Welcome to the MyBooking system!"<< endl;//setw(55)为预留55空间
cout<< " ----------------------------------------------------------"<< endl;
//1为买家,2为卖家,3为退出系统
cout<< right;//右对齐,默认为右对齐
cout<< endl<< setw(25)<< "1.Buyer"<< setw(15)<< "2.Seller"<< setw(15)<< "3.Exit"<< endl;
while (cin >>n)
{
order.clear();//什么访问什么来着?
menu.clear();
if (n == "3") break;
//处理错误输入
if (n != "1" && n != "2")
{
cout<< endl<< "Invalid number!Please input again :"<< endl;
cout<< endl<< setw(25)<< "1.Buyer"<< setw(15)<< "2.Seller"<< setw(15)<< "3.Exit"<< endl;
continue;
}

else seviceForSeller();

cout<< endl<< setw(25)<< "1.Buyer"<< setw(15)<< "2.Seller"<< setw(15)<< "3.Exit"<< endl;
}
return 0;
}
用于读取文件中的菜单和订单,需要用户提前输入好,储存在txt文本文档里
//用于读取文件中的菜单
Menu inputMenu()
{
Menu iMenu;
string dishID, dishName;
double price = -1;
finout >>dishID;
if (dishID == " " || dishID == "\n") {
iMenu.setDishID("-1");
return iMenu;
}
finout >>dishName >>price;
if (price< 0 || price >100000) {
iMenu.setDishID("-1");
return iMenu;
}
iMenu.setDishID(dishID);
iMenu.setDishName(dishName);
iMenu.setPrice(price);
return iMenu;
}
//用于读取文件中的订单
Order inputOrder()
{
string dishID, dishName, name, adress, phone;
double price = -1;
int year, month, day, hour, modify, num;
finout >>dishID;
if (dishID == " " || dishID == "\n")
{
Order iOrder;
iOrder.setDishID("-1");
return iOrder;
}
finout >>dishName >>price >>num >>name >>adress >>phone;
if (price< 0 || price >100000) {
Order iOrder;
iOrder.setDishID("-1");
return iOrder;
}
finout >>year >>month >>day >>hour >>modify;
Date date(year, month, day, hour);
