Last record added twice when reading ifstream

[Kenneth]

Ok, so logically this code seems to make sense but for some reason it
reads the last record twice before hitting eof. Is ifstream.eof()
implementation dependent?

void LoadFile(ifstream &File, List &List)
{
User lUser;
while(!File.eof())
{
File >> lUser;
List.insert(lUser,List.nodeCount());
}
}

This is an FAQ (I'd even say one of the most F AQs).
It's answered in the C++ FAQ lite at http://www.parashift.com/c++-faq-lite .
