在64位操作系统下（LP64 / LLP64 模型），下面代码的输出结果是（）。
#include <iostream>using namespace std; int main() { int a[4] = {1, 2, 3, 4}; int (*p)[4] = &a; int *q = a; cout << sizeof(a) << " "; cout << sizeof(p) << " "; cout << sizeof(p + 1) << " "; cout << sizeof(q + 1) << " "; cout << (p + 1) - p << " "; cout << (q + 1) - q << endl;}
