next operator in Perl skips the current loop execution and transfers the iterator to the value specified by the next. If there's a label specified in the program, then execution skips to the next iteration identified by the Label.
perl Perl
Syntax : next LabelExample 1:
#!/usr/bin/perl -w
# Perl Program to find the frequency
# of an element
@Array = ('G', 'E', 'E', 'K', 'S');
$c = 0;
foreach $key (@Array)
{
if($key eq 'E')
{
$c = $c + 1;
}
next;
}
print "Frequency of E in the Array: $c";
Output:
Example 2:
Frequency of E in the Array: 2
#!/usr/bin/perl
$i = 0;
# label for outer loop
outer:
while ( $i < 3 ) {
$j = 0;
while ( $j < 3 ) {
# Printing values of i and j
print "i = $i and j = $j\n";
# Skipping the loop if i==j
if ( $j == $i ) {
$i = $i + 1;
print "As i == j, hence going back to outer loop\n\n";
# Using next to skip the iteration
next outer;
}
$j = $j + 1;
}
$i = $i + 1;
}# end of outer loop
Output:
i = 0 and j = 0 As i == j, hence going back to outer loop i = 1 and j = 0 i = 1 and j = 1 As i == j, hence going back to outer loop i = 2 and j = 0 i = 2 and j = 1 i = 2 and j = 2 As i == j, hence going back to outer loop
