Hi Monks,
I wrote the following perl script to calculate the total marks, percentage and the pass/fail status of the students list. Here i have to calculate the rank of the students.
Your suggestions to approach this will be helpful at this point of time.
student.pl
----------
#!/usr/bin/perl
use strict;
use warnings;
open(FILE, "marks.txt") || die("cannot access the file");
my($fullname,$markseachsubject,$totalmarks,$percentage,@marks,@total,$
+marks,$status,@rank,$mark,$value,%records);
while(my $line=<FILE>){
next if $line=~/^NAME/;
chomp($line);
$line=~/(\w+),(\w+),(\d+),(\d+),(\d+)/;
$fullname=$1." ".$2;
push(@marks,$3,$4,$5);
foreach $mark(@marks){
$status=checkpass($mark);
}
$markseachsubject=$3." ".$4." ".$5." ".$status;
$totalmarks=$3+$4+$5;
@total=$totalmarks;
$percentage=$totalmarks/3; $percentag
+e=sprintf("%.2f",$percentage);
if($status eq "Pass"){
print $fullname." "."\t".$markseachsubject." "."\t".$totalm
+arks." "."\t".$percentage;
print "\n";
}else{
print $fullname." "."\t".$markseachsubject." "."\t";
print "\n";
}
}
#To check whether the student is pass or fail
sub checkpass{
$marks=shift;
if ($marks > 35){
$status="Pass";
return $status;
}else{
$status="Fail";
return $status;
}
}
close FILE;
My input file is:
marks.txt
----------
NAME:SURNAME:MARK1:MARK2:MARK3
john,michael,100,50,60
sam,shane,50,60,70
tom,christo,30,40,50
Thanks all for your help
