Hello,
Hello,
I would like to know how to test for the last element of a list during
a foreach loop, e.g.
foreach $element (@List) {
if (this is the last element) {
do something
}
}
What would I use for the IF condition?
You can't because a list does not have a name.
perldoc -q "What is the difference between a list and an array"
You can however do it with an array by comparing references:
$ perl -le'
my @x = "a" .. "z";
for my $elem ( @x ) {
print $elem if \$elem == \$x[-1];
}
'
z
