Question

$receiver is returning 1.

print "Who is receiving this message?:";
my $receiver = chomp(my $r = <STDIN>);
print $receiver;

Also, where can I find some more documentation about chomp? Thank you.

Answer 1

chomp returns the number of input record separator (whatever is in $/) characters removed from the end of each string in its argument list. It should be used:

chomp(my $reciever = <STDIN>);

chomp can be used on arrays and lists, which is, I assume, the reason for this functionality:

my $count = chomp(@array);

The documentation for chomp is in perldoc -f chomp
