为什么我只为一个元素分配内存？

...
        double * dd = (double*)malloc(size*sizeof (double));
        std::cout << "multiple void dd " << sizeof (dd)/sizeof (double) << " size "<< size <<std::endl;
...
run

multiple void dd 1 size 2625

修复的第二个实现：

...
    double * dd = new double (size);
    free(dd);
    double dd1 = *dd;;
    std::cout << "multiple void dd1 " << sizeof (dd1)/sizeof (double) << " size "<< size <<std::endl;
...

run

multiple void dd1 1 size 2625

我的行动：

sudo apt install python3.7
sudo apt install python-pip
pip install --user stdin
pip install --user serial
pip install --user numpy

python3.7
>>> ar2.py
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'ar2' is not defined

来源

在 Windows 7 中，由于某种原因，ubuntu 18.04 x64 没有问题，它不起作用。
