商店销售管理系统

吉林电子信息职业技术学院JiLin Technical College of Electronic Information 课程实训课程名称：C语言实训题目：商店销售管理系统系部：计算机系班级：软件09-1班实训者：于金民学号： 3指导教师：齐宁实训时间：2010.7.5 —— 2010.7.9吉林电子信息职业技术学院课程实训任务书*注：此任务书由课程设计指导教师填写。

一、实训题目商店销售管理系统二、功能概述屏幕上出现一个界面，让售货员输入商品编号或者商品名称，可以进货，进货后商品库存同时增加。

顾客买走商品后，售货员输入商品编号或者商品名称，可以生成销售清单，统计本次销售总的价钱，同时库存数量相应减少。

完成前面的基本功能后，还可以完成增加新的商品或删除不需要的商品的功能，以及每天销售统计功能等。

三、功能函数简介1.void jin—采购商品2.void mai—出售商品3.void xian1—显示商品清单4.void xian—显示商品信息5.void ku—显示库存信息6.void gai—修改商品信息四、程序流程图1.功能模块图2.程序流程图显示商品列表输出库存信息输入采购商品信息输入出售商品信息输入添加商品信息输入删除商品信息开始输出界面输入需要执行的操作选择操作采购商品出售商品查看商品列表查看库存修改商品列表推出五、程序代码#include"stdio.h"struct good{int num;char name[20];float price;int

语言的实训，经过一个星期的实训，让我了解了更深入的了解了关于C语言的知识，很让人受益匪浅，懂得如何去运用，而进行的一次分析设计综合的训练。
