	In addition to what everyone else has said about setting aside
space for username before using it and avoiding scanf in situations like
this to begin with:

	Also bear in mind that scanf expects a (char *), not a (char
**). So correct code would look more like:

main ()
{
  char username[20];

  scanf ("%s", username);
}

	That is, pass username itself to scanf. Don't pass &username; that
does the wrong thing.
