是否可以在内存中获取内存地址？

Question

I know that we can read the location/position of a variable and its value in the memory but I want to go more deeper to see where is this memory address located if it is possible. In my case 0x61fe09 is the memory address for a and what is the memory address for 0x61fe09 .

code:

    #include <iostream>
    using namespace std;

int main()
{
  int a = 42;
  int* adress_of_a = &a;
  int** adress_of_adress_of_a = &adress_of_a;
  cout << " a = " << a << " at memory address = " << &adress_of_adress_of_a << '\n';
  return 0;
}

Answer 1

There's no memory address for &a because it's not stored in memory.

You could store it in memory like so:

int* pointer_to_a = &a;

Now you can print &pointer_to_a to see the address where you stored &a .
