  Syntax:   switch( expression )
             {
                 [case constant-expression:]
                 ∙ ∙ ∙
                    [statement]
                 ∙ ∙ ∙

                    statement]
             }
 
  Summary:   Evaluates <expression> and executes any statement
             associated with <constant-expression> whose value matches
             the initial expression. If there is no match with a
             constant expression, the statement associated with the
             default keyword is executed. If the default keyword is not
             used, control passes to the statement following the switch
             block.
