超市管理系统的重构及优化

一、程序来源

　　本次的程序来源于同学之前完成的大作业，是超市物资管理系统，在对超市物资进行管理的基础上做了部分修改，增加了对于超市后续开分店等对超市的这一事物进行的管理。

二、运行环境和运行结果的截图（代码附加）

  1. 运行环境如下：

  1. 原程序的主要功能如下：

进入程序后首先进入超市管理系统的欢迎界面，效果如下：

A-主要功能

选择 1 “管理物资”后，输入之前创建的超市名称，可以进入对应超市的管理系统，选择对应的操作，按照商品的类别对超市物资进行管理；

其中增加商品分为增加商品类别和增加商品数量两种，会在进入选择后进一步划分；

之后按照类别或者商品名称进行操作即可，以下以增加商品为例进行展示；

选择 2 “创建新店”后，可以输入超市名称以创建新店铺，创建成功后会给出提示，并且展示特效。

选择 3 “退出系统”后，则直接退出当前的管理系统。

除了以上的基本功能外，系统还有一些细节的地方，比如增加商品数量时，若是输入的商品不存在，则会给出提示；操作完毕后，会给出选择，是在当前的主菜单继续操作，还是返回之前的主菜单进行操作等等。

源代码如下：

三、主要问题列表以及相应问题的改善与重构

 

既然系统提出了开新店的想法，那么在实际生活中，商家开新店必然会涉及店铺的转让、合并等操作，从实际应用的角度出发，给当前的系统增加了合并店铺、解散店铺等操作；

对于有保质期的商品，也应该增加商品的生产日期，以方便后续查看商品是否过期；

以下是主要的问题清单：

问题

问题描述

解决方案

问题一

没有对超市进行管理的功能，实际使用中设计店铺的问题会很麻烦

增加对超市进行管理的功能，增加开新店、查询店铺、合并店铺等操作

问题二

对于有保质期的物品，没有生产日期作为参考，不便于超市经营者进行管理

增加商品和查看商品时增加对保质期的记录和显示

 

四、重构的代码

修改后的代码主要是超市类的头文件和实现文件发生改变，以及对于基类Goods的.h文件和各个商品类的.h、.cpp文件、欢迎界面等进行修改，修改后的代码如下：

  1. Supermarket.h

五、重构后的代码测试

首先是对于超市管理功能的增加，可见效果图如下：

新增了解散店铺、合并店铺和查看已有店铺，具体功能实现细节如下：

  1. 解散店铺

  1. 合并店铺

  1. 查看已有店铺

接下来是关于增加商品和查看商品是可以记录和查看生产日期，具体实现如下：

(1)增加商品

 （2）查看商品

 六、总结

本次对于超市购物系统的修改和优化主要是从实际应用的角度出发，但其实还有很多可以修改的地方，比如程序运行时界面的转换（清屏函数的使用）、商品名称相同保质期不同时对于查询的要求等，这些都是可以进一步修改的地方，本次精力有限，主要是为了容器练手，目前只做了以上一些改善。

这里还发现了一个小细节，开第一家超市时的特效和后续开店的特效效果是不一样的，算是一个小惊喜。

第一次写这样长的博客，从3.3开始到3.5结束，主要很久没有写代码了，还是手生了都，留个戳做纪念。☆*: .｡. o(≧▽≦)o .｡.:*☆
