Here is a snippet of strangely mis-behaving code.

file "test.txt" contains numbers separated by white space, e.g. 1 2 3
4 5
one would expect the output to screen to be identical, but it turns
out to be 1 2 3 4 5 5.
It makes no difference if the white space precedes or succeeds the
number or both.
can someone explain?  Thanks.
float n;
ifstream in("test.txt");
   if(!in){cout<<"Can't open file."; getch(); return 1;}
   while(in){in>>n;
                 cout<<n<<"  ";}
