Page 200: The text states that the address of int x prints 0, which is wrong.

In the following text:

The address refers to the address of x ➊ and prints 0 ➋.

The statement is wrong as worded.

The code actually prints a non-zero address for x (in this case 0x000000F79DCFFB74), but then later also prints a nullptr as a hex string which ends up being 0x0000000000000000.
