仓库管理系统(c语言)

作品名称开发者：一、系统背景：本软件能减轻对货物数目管理及价格盈亏等信息处理的工作量以便能快捷及时准确的调整货物的仓储量达到最合理化。

可以使店主不失效率的节省大量精力用于其他方面符合当今社会的商业形式而且本软件体积小操作简单是管理仓库的不二选择二、系统简介：设计亮点：◆三级菜单使操作更简便明了◆密码操作能有效保证客户信息的安全性◆独特的dos命令调用使信息存储的实体属性为隐藏且无扩展名大大增大了安全系数◆数据结构为链表摆脱了数据数量的限制◆提供三种查看模式并会标出排名◆退出店主模式时会提示是否保存若选择yes着进行保存操作基本功能：·在员工模式下可输入卖出货物的名称和数目程序自动在后台进行一系列的操作·新建数据并同时对其处理·修改数据·插入数据·删除数据·查找数据·查看数据·数据存档·修改密码三、系统结构图#define LEN sizeof(struct shop)#include<stdio.h>#include<conio.h>#include<string.h>#include<stdlib.h>struct shop{char name[30];float price_in;float price_out;int num_in;int num_now;int num_sold;float win;float percent;struct shop *next;};int n=0;void main(void){void auto1(struct shop **h_p);int menu1(struct shop **h_p);void print1(void);void assistant(struct shop *head);int password(void);int menu2(struct shop **h_p);void print2(void);void creat(struct shop **h_p);void rewrite(struct shop **h_p);void insert(struct shop **h_p);void deleat(struct shop **h_p);void search(struct shop **h_p);void printall(struct shop **h_p);void save(struct shop *head);void password_set(void);int password_exi(struct shop **h_p);int data_exi(struct shop **h_p);void load(struct shop **h_p);void save(struct shop *head);struct shop *addbuild(struct shop **h_p);
