先输出[1] apples
[2] pears
[3] oranges
[4] grapes
[0] Exit
在计算price
cout<<"[1] apples"<<endl;
cout<<"[2] pears"<<endl;
cout<<"[3] oranges"<<endl;
cout<<"[4] grapes"<<endl;
cout<<"[0] Exit"<<endl;
cin>>n;
if(n!=0)cout<<"price=";
if(n==1) cout<<"3.0";
else if(n==2) cout<<"2.5";
else if(n==3) cout<<"4.5";
else if(n==4) cout<<"9.5";
else if(n!=0) cout<<0;
