来源:本站原创|时间:2020-01-10|栏目:C语言|点击:

本文实例为大家分享了C语言点菜系统的具体代码,供大家参考,具体内容如下

用C语言编写的简单的餐厅点菜系统,操作简单,代码不多,菜单可以自己更改,价格也是

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
#include"windows.h"

 int price;
};

struct List /*该线性表实现对菜品原材料的剩余量的记录,线性表【i】对应菜品的点餐菜单编码*/
{ 
 ElemType* list;
 int size;
 int MaxSize;
};
/*以下为线性表的函数*/
