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<cstdlib>
using namespace std;

system("cls");
int p,q,sum=0;
string name[]={"遙控汽車","飛機模型","足球 ","拼圖 ","玩具槍 ","可愛玩偶","籃球 "};
int price[]={450,550,325,200,660,150,380};
cout<<"☆★☆智能玩具店☆★☆"<<endl<<endl;
cout<<"[商品價目表]"<<endl;
for(int i=0; i<7; i++)
cout<<"("<<i+1<<")"<<name[i]<<"\t"<<price[i]<<"元"<<endl;
cout<<"(8)結帳"<<endl<<endl;
re2:
cout<<"請輸入商品代碼: ";
cin>>p;
if(p==8)
{
goto checkout;
}else if(p>=1 && p<=7)
{
cout<<"數量: ";
cin>>q;
sum+=price[p-1]*q;
goto re2;
}else
