数组名和指针

    const int sz = 10;
    int arr[10] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
    auto pBegin = begin(arr);
    auto pEnd = end(arr);

    while (pBegin != pEnd)
    {
        cout << *pBegin << " ";
        pBegin++;//这里指针移动了
    }

    cout << endl;
    pBegin = begin(arr);//重新获取指针
    pEnd = end(arr);
    while (pBegin != pEnd)
    {
        *pBegin = 0;

        pBegin++;//指针移动了
    }

    pBegin = begin(arr);//重新获取指针
    pEnd = end(arr);
    while (pBegin != pEnd)
    {
        cout << *pBegin << " ";
        pBegin++;
    }
