arithmetic operation in print

sedawk · Jun 25, 2006

I want print an arithmetic equation in a print command, for example.

Code:

for (my $i = 0 ; $i < 4; $i++){
   print "the number is " . $i . "and the next one is " . $i+1;
}

But the compiler produced an error about arithmetic operation. How to do that?

Thanks

Code:

for (my $i = 0 ; $i < 4; $i++){
   print "the number is " . $i . " and the next one is " . ($i+1)."\n";
}

just a twist on how to do this:

Code:

for (my $i = 0 ; $i < 4; $i++){
   print "the number is $i and the next one is @{[$i+1]}\n";
}
