這篇文章主要為大家詳細(xì)介紹了基于C語言實現(xiàn)點菜系統(tǒng)，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了C語言點菜系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

用C語言編寫的簡單的餐廳點菜系統(tǒng)，操作簡單，代碼不多，菜單可以自己更改，價格也是

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
#include"windows.h"
struct cai /*cai結(jié)構(gòu)體 實現(xiàn)對菜品 已點份數(shù)、名稱、原材料 的記錄*/
{
 int fenshu;
 char name[50];
 int use;
 int price;
};
typedef int ElemType;
struct List /*該線性表實現(xiàn)對菜品原材料的剩余量的記錄，線性表【i】對應(yīng)菜品的點餐菜單編碼*/
{ 
 ElemType* list;
 int size;
 int MaxSize;
};
/*以下為線性表的函數(shù)*/
void InitList(struct List* L,int ms)  
{
 if(ms<=0){printf("ms 值非法！\n");exit(1);}
 L->MaxSize=ms;
 L->list=malloc(ms*sizeof(ElemType));

  exit(1);
