compile error about auto_ptr

Hello everyone,


I am confused to read what the compiler says. Could anyone explain what
it means?


Code:
--------------------

#include <memory>
#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;

int main( )
{
int i = 0;

vector<auto_ptr<int>> vc;
for (i = 0; i < 5; i ++) // 0 1 2 3 4
{
auto_ptr<int> pi (new int(i));
vc.push_back (pi);
}

return 0;
}

--------------------
