@ -245,7 +245,13 @@ cout << fooRef; // Prints "I am foo. Hi!"
// Doesn't reassign "fooRef". This is the same as "foo = bar", and
// foo == "I am bar"
// after this line.
cout << &fooRef << endl; //Prints address of fooRef
fooRef = bar;
cout << &fooRef << endl; //Prints address of fooRef, AGAIN
cout << fooRef; // Prints "I am bar"
//The address of fooRef remains the same, i.e. it is still referring to foo.
const string& barRef = bar; // Create a const reference to bar.
// Like C, const values (and pointers and references) cannot be modified.
