i wrote this code to find the nCr of a no. in perl 5 in windows.
i have used subroutines. but since i used it for first time(specified in college assignemnt ) i im very good with it. any way, the program ran properly in windows.
now when i typed the code in our college ( clients on windows 98 connect to server on redhat 8 thru puttry telnet tool-perl there too is version 5.xx)
it simply didnt budge. someone said subroutine isnt returning value. so made necesarry changes and sat for 3 hrs but program just didnt run.
when i run the same program(whihc wrote at home in windows perl) in mandrake 10.1 at home, it runs and no errors too. SO WHY DIDNT IT RUN IN RED HAT 8 IN COLLEGE.
PLZ HELP ME

SAVE THIS CODE in notepad as ncr.pl and in console(dos or linux)
note: give values in command line while running
ex:
type at prompt ($) perl ncr.pl 12 8
to find 12C8
remove the first line if running in windows
Code:
#! /usr/bin/perl
system "clear";
print "\nProgram Name=> nCr \n";
$n=$ARGV[0];
$r=$ARGV[1];
chomp $n;
chomp $r;
if($n<$r || $n<0 || $r<0)
{
print "\n U MORON, n cannot be < r or -ve. Enter again\n";
}
else
{
print "\n n= $n\n";
print "\n r= $r\n";
$nfact=1;
$rfact=1;
$nrfact=1;
&fact($n,$r);
print "\n n!= $nfact\n";
print "\n r!= $rfact\n";
print "\n (n-r)!= $nrfact\n";
$l=$rfact*$nrfact;
print "\n r!*(n-r)!= $l\n";
$m=$nfact/$l;
print "\n Formula for nCr=n!/(r!*(n-r)!) \n";
print "\n nCr=$n!/($r!*($n-$r)!)=$m \n";
}
sub fact
{
for($i=1;$i<=$n;$i++)
{
$nfact*=$i;
}
for($j=1;$j<=$r;$j++)
{
$rfact*=$j;
}
for($k=1;$k<=($n-$r);$k++)
{
$nrfact*=$k;
}
}
