checking if this is a typo in the C++ book

Hi! I'm trying to learn C++ and would like to check if this is a typo from page 135 of the ebook as it's really confusing me.

Is the 2nd line of the code supposed to be this?

int *p_x = & x;

Or is it also ok to declare pointers without the *?

Thanks!

Your correction is correct!

Thank you! :)
