                          Loop Control Statements
                          Loop  control  statements  change  execution  from  its  normal  sequence.  When  execution
                   leaves a scope, all automatic objects that were created in that scope are destroyed.
                          C supports the following control statements.



                             Control Statement          Description


                             break statement            Terminates  the  loop  or  switch  statement  and  transfers
                                                execution  to  the  statement  immediately  following  the  loop  or
                                                switch.


                             continue statement         Causes the loop to skip the remainder of its body and
                                                immediately retest its condition prior to reiterating.


                             goto statement             Transfers control to the labeled statement.


                          break Statement
                          The break statement in C programming has the following two usages:
                                       When  a  break  statement  is  encountered  inside  a  loop,  the  loop  is
                   immediately terminated and the program control resumes at the next statement following the loop.
                                       It can be used to terminate a case in the switch statement (covered in the
                   next chapter).
                          If you are using nested loops, the break statement will stop the execution of the innermost
                   loop and start executing the next line of code after the block.

                          Syntax
                          The syntax for a break statement in C is as follows:

                 break;
