What will be the output of the following C++ code?

#include <iostream>
#include <memory>
#include <string>
using namespace std;
int main () 
{
    pair <string*, ptrdiff_t>
    result = get_temporary_buffer<string>(3);
    if (result.second > 0)
    {
        uninitialized_fill ( result.first, result.first + result.second, 
        "Hai" );
        for (int i=0; i<result.second; i++)
            cout << result.first[i] ;
        return_temporary_buffer(result.first);
    }
    return 0;
}
