Perl last statement
Perl loopsThe Perl last statement is used to exit the loop statement block, thereby ending the loop. Statements after the last statement are no longer executed, and the continue statement block is also no longer executed.

Example
#!/usr/bin/perl
$a = 10;
while( $a < 20 ){
if( $a == 15)
{
# Exit the loop
$a = $a + 1;
last;
}
print "The value of a is:$a\n";
$a = $a + 1;
}
Executing the above program produces the following result:
a 的值为: 10 a 的值为: 11 a 的值为: 12 a 的值为: 13 a 的值为: 14Other extensions
