C++正确的cin输入

void test1(void)
{
	int number;
	cout << ">> pls input a integer number:";
	while(cin >> number, !cin.eof())
	{
		if(cin.bad()) {
			cout << "stream has corrupted!" << endl;
			return;
		} else if (cin.fail()) {
			cin.clear();
			cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
			cout << ">> pls input a integer number:";
			continue;
		}
		cout << "number = " << number << endl;
	}
}
