What is the different between *&aPtr and &*aPtr?

Question

I want to know what is the different between *&aPtr and &*aPtr if replaced * & and & * ?

int a;   
int *aptr;  
a = 7;     
aptr=&a;

cout << &* aPtr<< *&aPtr<< endl;

Answer 1

They have the same value, but *&aPtr is an lvalue that refers to aPtr whereas &*aPtr is a prvalue that has the same value as aPtr.
