const int NUM = 5;

void show(double d)
{
    cout << d << " ";
}

int main(void)
{
    vector<double> scores = { 11,23 };
    //第一种遍历方式
    for (auto pd = scores.begin(); pd != scores.end(); pd++)
    {
        cout << *pd << " ";
    }
    cout << endl;
    double temp = 5;
    scores.push_back(temp);

    //第二种遍历方式
    for_each(scores.begin(), scores.end(), show);
    cout << endl;

    //第三种遍历方式
    for (auto score : scores)
