// auto_ptr::operator* example
#include <iostream>
#include <memory>
using namespace std;

int main () {
  auto_ptr<int> p1 (new int (10));
  auto_ptr<int> p2 (new int);

  *p2 = *p1 * 2;

  cout << "p1 points to: " << *p1 << "\n";
  cout << "p2 points to: " << *p2 << "\n";

  return 0;
}


Output:

p1 points to: 10
p2 points to: 20
