c++ - failed to move contents with std::move -

-

i'm trying understand how std::move simple example (below). i'm trying move contents of p1 p2, p1 empty after that, doesn't happen though.

i guess i'm not using std::move properly. appreciate lot if explain me.

#include <iostream> #include <utility>  int main() {     int * p1 = new int[10];     for(int = 0; < 10; ++i)         p1[i]=i;     // moving contents of p1 p2       int * p2 = std::move(p1);        // expeting p1 empty it's not...     if(p1 != null)         std::cout << "i'm not empty\n";     // prints i'm not empty      }

the move function not guaranteed clear contents of source object. is, however, guaranteed left in such state can safely destroy or assign new value it.
