[問題] 陷入無限迴圈
有請高手幫我指正以下的程式碼。
我想要寫一個程式可以輸入成績等級A B C。最後統計各個等級的總人數。
cout << "請輸入成績等級: " << endl << "若想停止請輸入EOF" << endl;
while ( (grade = cin.get()) != EOF ){
switch ( grade ){
case 'A':
case 'a':
acounter = acounter + 1;
break;
case 'B':
case 'b':
bcounter = bcounter + 1;
break;
case 'C':
case 'c':
ccounter = ccounter + 1;
break;
case '\n':
case '\t':
case ' ':
break;
default:
cout << "Incorrect letter grade entered."
<< "Enter a new grade." << endl;
break;
}
}
cout << "\n\n每項成績的人數為: "
<< "\nA: " << acounter
<< "\nB: " << bcounter
<< "\nC: " << ccounter;
return 0;
}
如果使用EOF進行終止，編譯器會說EOF沒有宣告，如果使用-1又會變成無線迴圈。
觀念不清，請大家指正了 > <
