新增 "請輸入商品代碼:" 與 "數量:" 的選項,
並於結帳時計算出
總共多少錢
,執行畫面如下圖所示。
#include<iostream>
#include<cstdlib>
using namespace std;
int main()

//商品名稱
string name[]={"遙控汽車","飛機模型","足球\t","拼圖\t","玩具槍","可愛玩偶","籃球\t"};
//商品價格
int price[]={450,550,325,200,660,150,380};
cout<<"☆★☆智能玩具店☆★☆"<<endl<<endl;
cout<<"[商品價目表]"<<endl;
//把選項|名稱|價格輸出
for(int i=0;i<=6;i++)
{
cout<<"("<<i+1<<")"<<name[i]<<"\t"<<price[i]<<endl;
}
cout<<"(8)結帳"<<endl;
int option,qty,sum=0;
re:
cout<<"你要買什麼?";
cin>>option;
//1~7
if(option>=1 and option<=7)
{
//購物
cout<<"你要買幾個?";
