Loop Control Statements in Perl
Loop control statements change the execution from its normal sequence. When execution leaves a scope, all automatic objects that were created in that scope are destroyed.
Perl supports the following control statements. Click the following links to check their detail.
| Sr.No. | Control Statement & Description |
|---|---|
| 1 | next statement It causes the loop to skip the remainder of its body and immediately retest its condition prior to reiterating. |
| 2 | last statement Terminates the loop statement and transfers execution to the statement immediately following the loop. |
| 3 | continue statement A continue BLOCK, it is always executed just before the conditional is about to be evaluated again. |
| 4 | redo statement The redo command restarts the loop block without evaluating the conditional again. The continue block, if any, is not executed. |
| 5 | goto statement Perl supports a goto command with three forms: goto label, goto expr, and goto &name. |
