Ⅰ c语言菜单点菜并计算价格问题
输出的格式对齐你自己可以调一下，程序本身没有任何问题。
程序是在Visual Studio 2008上编译运行的。
#include "stdafx.h"
#include <iostream>
#include <vector>
#include <string>
using namespace std;
char menu[6][8][16]={
{"菜单","开胃菜","主菜","主食","饭后甜点","饮料"},
{"开 胃 菜","烧椒皮蛋","蓝莓山药墩","竹笋干炒肉","干煎野山菌","小炒黄牛肉"},
{"主 菜","菠萝古老肉","水煮鱼","茄汁基围虾","盐焗手撕鸡","红烧黄花鱼","蚝油生菜","金牌蒜香骨"},
{"主 食","三鲜水饺","手擀面","米饭"},
{"饭后甜点","草莓奶昔","冰激凌","蛋糕"},
{"饮 料","雪碧","蔬菜汁","啤酒","果汁"},
};
double price[6][8]={
{0},
{0,8,10,8,13,12},
{0,15,20,35,30,28,8,18},
{0,15,12,2},
{0,10,16,10},
{0,5,8,8,8}
};
vector<int> menuvec; //保存选了那些菜单项
vector<int> foodvec; //保存选了那些食物
vector<int> countvec; //保存每个食物都选了几份
bool dinner()
{
for(int i = 0; i < 6; i++)
{
if (i == 0)
{
cout << menu[0][i] ;
cout<<":"<<endl;
}
else
{
cout << " " << i << ".";
cout << menu[0][i] << endl;
}
}
cout <<" "<<"0点餐结束"<<endl;
int imenu = 0; //选择菜单项
cout << "请选择 ";
cin >> imenu;
if (imenu == 0)
return false;
cout << " "<< imenu << "." << menu[0][imenu] << endl;
for(int i = 1; i < 8 ; i ++)
{
if (strcmp(menu[imenu][i],"") == 0)//如果没有此项食物则退出输出
break;
cout << " "<< i << "." << menu[imenu][i] << " " << price[imenu][i] << endl;
}
cout <<" 0 返回" << endl;
int ifood = 0;//选择要点的食物
int icount = 0;//选择要点的食物的份数
cout << "请选择";
cin >> ifood ;
if (ifood == 0)
return true;
cout <<"你点的是" << menu[imenu][ifood] << ","<<"请问你要几分：";
cin >> icount;
menuvec.push_back(imenu);
foodvec.push_back(ifood);
countvec.push_back(icount);
return true;
}
int main()
{
while(dinner())
{
system("cls");
}
system("cls");
cout << "你点的菜单是：" << endl;
cout << " 菜名 "<<" 单价 "<<" 数量 " <<" 价格 "<< endl;
vector<int>::iterator menuIter = menuvec.begin();
vector<int>::iterator foodIter = foodvec.begin();
vector<int>::iterator countIter = countvec.begin();
double pricesum = 0; //计算总价钱
for(;menuIter != menuvec.end(),foodIter!= foodvec.end(),countIter != countvec.end();menuIter++,foodIter++,countIter++)
{
int menutemp = *menuIter;
cout << menu[0][menutemp];
cout << ":";
int foodtemp = *foodIter;
cout << menu[menutemp][foodtemp];
cout << " " << price[menutemp][foodtemp];
int counttemp = *countIter;
cout << " "<<counttemp;
cout << " "<< counttemp*price[menutemp][foodtemp] << endl;
pricesum += counttemp*price[menutemp][foodtemp] ;
}
cout <<"-----------------------------------------------------------------------------"<<endl;
cout << " "<<"总价是 "<< pricesum << endl;
}
Ⅱ 用C语言为学校食堂做一个点菜系统,当用户选择自己喜欢的菜,所消费的钱就能显示出来。 菜谱封面如下：
#include <stdio.h>
void main()
{
int a[4],i,j,m;
char t;
printf(”********************************* \n1.红烧肉5.0元2.炸鸡翅3.0元\n3.炒芹菜2.0元4.五香蛋1.0元\n5.退出\n********************************\n\n”);
printf(“请输入您点的菜\n”);
for(i=0;i<=3;i++)
{ scanf(“%d”,&a[i]);j=i;
if(i<=2)
{ printf(“是否继续点菜\n回复Y OR N\n”);
scanf(“%c”,&t);
if(t==Y)
continue;
else if(t==N){j=i;break;}
else {printf(“error,自动结算\n”);j=i;break;}}
}
for(i=0,m=0;i<=j;i++)
m=m+a[i];
printf(“总金额%d\n”,m);
}
//手机编写，错误难免，问题不大，多多包含
Ⅲ c语言编程实现：有30个人，其中有男人，女人，小孩，在一家餐厅消费了500元，其中每个男孩人消费3
#include main(){ int x=0,y=0,z=0; for(x=0;x
Ⅳ C语言编写点菜系统
简单的点菜系统，可供学习：

if (argc < 2)

"); exit(1); }

//愿意接收连接

while(1)
{

printf("received a connection from %s\
", inet_ntoa(remote_addr.sin_addr));
if (!fork()) { /* 子进程代码段 */

", 26, 0) == -1)
perror("send"); close(client_fd); exit(0); }
close(client_fd); }
return 0;
}
