in reply to fibonacci numbers using subroutine?

You can easily do it in subroutine.If you don't understand the following code, you read about it.Subroutine is very useful for coding.It simplifies your program as well as it avoids the repetition of statements.

print "Enter the number you would like to see in the sequence: "; my $number = <STDIN>; &fibonacci($number); #calling the subrounting fibonacci with passing g +iven number as argument sub fibonacci { my $a = 0; my $b = 1; # So now we see the parameter being used here. For clarity, I have w +ritten the for # loop using $n like the other examples. To set $n using the first p +arameter passed # to the subroutine, I access the scalar variable $_[0], which is th +e first element # of the parameter array @_ my $n = $_[0]; for (my $i=0;$i<$n;$i++){ #for loop to traverse and find the sum of +the value printf "%d\n", $a; my $sum = $a + $b; $a = $b; $b = $sum; } }

[marto]: 1nickt it depends on the people on the plane I guess. On a related note I'm unsure why they sell booze on planes & airports, seems like a bad mix to me. Profit before sanity I guess
