用C語言編寫一簡單的商品銷售管理系統

第一個功能商品入庫其實就是輸入數據 不要想得太複雜 直接用scanf輸入就可以了

第二個商品銷售 就是改一下商品的數量

查詢用折半查找順序查找都可以 查到之後printf

排序可以用選擇法

用C語言編寫“銷售管理系統設計”程序

講下設計思想吧

便條實際上包含了登陸信息了，所以省去了登陸環節，簡單點做到如下幾點就可以 了：

1、調用c的圖形類創建一菜單，有便條錄入、和信息查詢兩欄，信息查詢下面再分各種查詢

2、便條錄入可以都不用圖形界面了，直接按條目輸入值，順序輸入即可

3、保存以文件形式，可以在第一次建立個txt文檔，以製表符分割開來各個字段，但是每次寫入的時候必須按行作為一條數據，可以適當增加需要的字段作為查詢統計方便用（每個製表符分割的為一個字段）。

4、查詢統計就直接檢索這個txt文檔，該加總的求平均的用循環去查即可。

5、結果輸出即把查到的內容在屏幕上打印出來即可。

其他，如果用c++做就簡單多了，沒那麼多代碼寫
