新增 "購物清單" 功能,使結帳時能不只計算出價錢,還能列出細目。
參考執行畫面如下:
- #include<iostream>
- #include<cstdlib>
- using namespace std;
- int main()
- {
-
- 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;
-
- int p,q,sum;
- cout<<"請輸入商品代碼: ";
- cin>>p;
-
- while(p!=8){
- cout<<"數量: ";
- cin>>q;
- sum += price[p-1] * q;
-
- cout<<"請輸入商品代碼: ";
- cin>>p;
- }
-
- cout<<endl<<"[購物清單]"<<endl;
- cout<<"-----------------------------"<<endl;
-
- cout<<"-----------------------------"<<endl;
-
- cout<<endl<<"總共"<<sum<<"元!"<<endl;
-
-
- system("pause");
- return 0;
- }
