switch 判斷式
利用 switch 判斷式, 設計一成績分級程式, 分級方式如下:
80分~100分 甲等
70分~79分 乙等
60分~69分 丙等
0分~59分 不及格
不在以上範圍 輸入錯誤
[使用者介面如下]
請輸入你的成績: 77
乙等!
請輸入你的成績: 101
輸入錯誤!
#include<iostream>
#include<cstdlib>
using namespace std;
int main()
{
int score;
cout<<"請輸入你的成績: ";
cin>>score;
switch(score)
{
case 80 ... 100:
cout<<"甲等"<<endl;
break;
case 70 ... 79:
cout<<"乙等"<<endl;
break;
case 60 ... 69:
cout<<"丙等"<<endl;
break;
case 0 ... 59:
cout<<"不及格"<<endl;
break;
default:
cout<<"輸入錯誤"<<endl;
}
system("pause");
return 0;
}
