Off topic, but ....

* The  "switch"  statement causes control to be transferred to one of
 several statements depending on the value of a condition.

* Any statement within the switch statement can  be  labeled
  with one or more "case" labels as follows:
          "case constant-expression :"

* There shall be almost one label of the form
          "default :"

* When the switch statement is executed, its condition is evaluated  and
  compared  with  each  case  constant.  If one of the case constants is
  equal to the value of the condition, control is passed to  the
  statement  following  the  matched case label.  If no case constant 
  matches  the condition, and if there is a default label, control passes 
  to  the  statement  labeled  by  the  default label.  If no case matches 
  and if  there is no default then none of the statements in the switch is
  executed.

* To exit from a switch - case statement use "break;"
