using namespace std;

int main ()
{
 int firstvalue = 5, secondvalue = 15;
 int * p1, * p2;

 p1 = &firstvalue;  // p1 = address of firstvalue
 p2 = &secondvalue; // p2 = address of secondvalue
 *p1 = 10;          // value pointed to by p1 = 10
 *p2 = *p1;         // value pointed to by p2 = value pointed to by p1
 p1 = p2;           // p1 = p2 (value of pointer is copied)

 cout << firstvalue << '\n';
 cout << secondvalue << '\n';
 return 0;
