convert a reference variable into a pointer variable

You can’t declare a variable as a pointer to a reference, but we often take the address of a reference variable. I think it’s same as address of the referent.

Q: If you need to pass a pointer to a 3rd party library, but you only received a reference variable — perhaps as an function input argument, how?
A: Well, you can treat the variable as a non-ref and simply pass its address to the library.
