•   break statement Kernighan p224 (very bottom of page)

  A break statement may appear only in an iteration statement or a switch statement, and terminates execution of the smallest enclosing such statement; control passes to the statement following the terminating statement.

•   switch ( expression ) statement
  • expression must be integral.
  • all case constants must be unique.
  • all sub-statements must be labeled with one or more case labels.
  • Only one default statement is allowed.
  • If there is no break, execution continues into the next case.
  • Has the possibility of providing a very fast multi-way jump.

             switch( i )
              {
              case 1: a++;          /* falls into case 2 */
              case 2: b++; break;
              default: c++;         /* I was not 1 or 2 */
              }
          

•   continue statement Kernighan p224

  A continue statement may appear only within an iteration statement. It causes control to pass to the loop-continuation portion of the smallest enclosing such statement.
