#include <iostream>#include <memory>   struct Foo { Foo(int _val): val(_val){std::cout<<"Foo...\n";} ~Foo(){std::cout<<"~Foo...\n";}int val;};   int main(){std::unique_ptr<Foo> up1(new Foo(1));std::unique_ptr<Foo> up2(new Foo(2));   up1.swap(up2);   std::cout<<"up1->val:"<< up1->val <<std::endl;std::cout<<"up2->val:"<< up2->val <<std::endl;}

Output:

Foo... Foo... up1->val:2 up2->val:1 ~Foo... ~Foo...
