It is worth pointing out that, under modern operating systems, that
need does not exist.  Indeed, you must take special action to get
the backspaces, if you want to handle them yourself:

  Unless you are using a primitive system, backspace editing is not
  done within gets() itself; rather, it is done at a lower level (by
  the system).

To forestall further questions here, disabling and enabling this editing
is a function of the operating system, not the language, so there is no
single answer to `how do I do it in C'.
