用C语言编写一简单的商品销售管理系统
第一个功能商品入库其实就是输入数据 不要想得太复杂 直接用scanf输入就可以了
第二个商品销售 就是改一下商品的数量
查询用折半查找顺序查找都可以 查到之后printf
排序可以用选择法
用C语言编写“销售管理系统设计”程序
讲下设计思想吧
便条实际上包含了登陆信息了，所以省去了登陆环节，简单点做到如下几点就可以 了：
1、调用c的图形类创建一菜单，有便条录入、和信息查询两栏，信息查询下面再分各种查询
2、便条录入可以都不用图形界面了，直接按条目输入值，顺序输入即可
3、保存以文件形式，可以在第一次建立个txt文档，以制表符分割开来各个字段，但是每次写入的时候必须按行作为一条数据，可以适当增加需要的字段作为查询统计方便用（每个制表符分割的为一个字段）。
4、查询统计就直接检索这个txt文档，该加总的求平均的用循环去查即可。
5、结果输出即把查到的内容在屏幕上打印出来即可。
其他，如果用c++做就简单多了，没那么多代码写
