Programming Challenge 4.22 - Freezing And Boiling Points

/* Freezing And Boiling Points - The following table lists the freezing and
   boiling points of several substances.
  
   Substance                Freezing Point (°F)            Boiling Point (°F)
   Ethyl alcohol            -173                        172
   Mercury                    -38                            676
   Oxygen                    -362                        -306
   Water                    32                            212

   This program asks the user to enter a temperature and then shows all the
   substances that will freeze at that temperature and all that will boil at
   that temperature. For example, if the user enters -20 the program should
   report that water will freeze and oxygen will boil at that temperature. */
