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()
- {
- 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 = 0, sum = 0;
- while(true)
- {
- int count = 0;
- cout<<"請輸入商品代碼: ";
- cin>>p;
- if(p==8)
- break;
- cout<<"數量: ";
- cin>>count;
- sum = sum + price[p-1] * count;
- }
- cout<<endl<<"總共"<<sum<<"元"<<endl;
- system("pause");
