#include <iostream>
using std::cout;
using std::endl;

int main()
{
   int a;
   int *aPtr; 

   a = 7; 
   aPtr = &a;

   cout << "The address of a is " << &a << "\nThe value of aPtr is " << aPtr;
   cout << "\n\nThe value of a is " << a << "\nThe value of *aPtr is " << *aPtr;
   cout << "\n\nShowing that * and & are inverses of " << "each other.\n&*aPtr = " << &*aPtr
      << "\n*&aPtr = " << *&aPtr << endl;
   return 0;
}

The address of a is 0x22ff74
The value of aPtr is 0x22ff74

The value of a is 7
The value of *aPtr is 7

Showing that * and & are inverses of each other.
&*aPtr = 0x22ff74
*&aPtr = 0x22ff74
