As a two day learner of perl I've come across the following, basically I'm messing around with the examples in the O'reilly Learning Perl.
Use of uninitialized value at perky-array line 38, <> chunk 1.
The script still works but I get the following error when the 'loop' related to an unkown user kicks in ?
Can anyone help an (obvious) initiate:
#!/usr/bin/perl -w
###@words = ("camel", "llama", "alpaca");
###
### #or
### #@words = qw(camel llama alpaca); # qw acts to specify "" to each
+ variable
###
### Above shows the use of an 'array' - the following describes an 'ha
+sh'
### shown as %a (see 'pinky' for full program)
%words = qw (
fred camel
barney llama
betty alpaca
wilma alpaca
);
print "What is your name? ";
$name = <>;
chomp $name;
if
($name eq "pete")
{
print "Hello, $name! \n";
}
else
{
print "Hello $name,\n ";
$secretword = $words{$name}; # gets secret word
#### problem seems to start here #####
if ($secretword eq "")
{$secretword = "groucho"; }
print "What's the secret word ?\n";
$guess = <>;
chomp ($guess);
while ($guess ne $secretword)
{
print " Niet - try again, What is the secret word ?\n";
$guess = <>;
chomp ($guess);
}
}
