The continue statement passes control to the test portion of the
  immediately enclosing while, do, or for statement.
  Syntax:

       continue ;

  In each of the following statements, a continue statement is
  equivalent to "goto label;":

    while (expression) { statement ... label: ; }

    do { statement ... label: ; } while (expression);

    for (expression; expression; expression)
        { statement ... label: ; }

  The continue statement is not intended for switches.  A continue
  statement inside a switch statement inside a loop causes
  reiteration of the loop.
