Hey folks, pretty experienced program in other languages but I'm crash learning perl for a new job. Following O'Reilly's Llama book. Decided to try something for myself to see if i understand things properly. heres what I have:
my %hash = ("fred" => "flintstone", "dino" => undef, "barney" => "rubb
+le", "betty" => "rubble");
my @ky = keys %hash;
my @vals = values %hash;
printf "%10s\t=>%10s\n", "keys", "values";
printf "%10s\t=>%10s\n" x @ky, @ky, @vals;
So what I'm trying to do if you don't know from seeing the above is get output that looks like two columns, first row has "keys => values" the subsequent rows has the keys and values in their respective columns but what I'm getting instead is this:
keys => values
barney => betty
dino => fred
rubble => rubble
(but it's of course formatted correctly in neat columns..... web-struggles)
can someone tell me where I"m going wrong?
I've done something like this but using only a single conversion and an array but now I'm trying to do it with the two conversions and it's not working out for me.
