Using the Address-Of Operator (&) on References

You have now seen that the & symbol is used for both the address of a variable and to declare a reference. But what if you take the address of a reference variable? If you ask a reference for its address, it returns the address of its target. That is the nature of references. They are aliases for the target. Listing 9.2 demonstrates taking the address of a reference variable called rSomeRef.

10:
11:     intOne = 5;
12:     cout << "intOne: " << intOne << endl;
13:     cout << "rSomeRef: " << rSomeRef << endl;
14:
15:     cout << "&intOne: "  << &intOne << endl;
16:     cout << "&rSomeRef: " << &rSomeRef << endl;
