これが私のコードです:
int main()
{
int nothing;
string name;
int classnum;
bool classchosen;
string classname;
cout << "Welcome adventurer, your journey is about to begin.\n\n";
cout << "Firstly, what's your name? ";
cin >> name;
classchosen = false;
while (classchosen == false)
{
cout << "\n\nNow, " << name << ", choose your class entering its number.\n\n";
cout << "1- Warrior\n" << "2- Mage\n" << "3- Paladin\n" << "4- Monk\n\n";
cout << "Class number: ";
cin >> classnum;
switch(classnum){
case 1:
classname = "Warrior";
classchosen = true;
break;
case 2:
classname = "Mage";
classchosen = true;
break;
case 3:
classname = "Paladin";
classchosen = true;
break;
case 4:
classname = "Monk";
classchosen = true;
break;
default:
cout << "\nWrong choice, you have to enter a number between 1 and 4.\n" << endl;
break;
}
}
cout << "\nSo you are a " << classname << " ? Well, tell me something more about you...\n";
cin >> nothing;
return 0;
}
今、それを実行して文字列 (たとえば "fjdfhdk") を入力してクラス番号を尋ねると、プログラムはデフォルトのステートメントに入る代わりに無限ループし、質問を書き直して別のクラスを選択させます。なんで?
