switch的简单使用

#include<iostream>using namespace std;int main(){    int t;    while(cin>>t)    {        if(t>100||t<0)  cout<<"Score is error!"<<endl;        else        {            switch(t/10)            {                case 10:                case 9:cout<<'A'<<endl;break;                case 8:cout<<'B'<<endl;break;                case 7:cout<<'C'<<endl;break;                case 6:cout<<'D'<<endl;break;                default:cout<<'E'<<endl;            }                    }    }    return 0;}
