Dear Monks,
I have written this program which is supposed (Update!) TO WRITE TO AN EXCEL file a new set of records, everytime it runs, it works fine the first time I run it, the second time I run it though, it does not append records to the file like it is supposed to, (UPDATE!) I mean it does not update the excel file with new sets of records, in fact it does not add anything and I notice that the excel file size would increase everytime I run the program even though it does not append...
I am aware that in programming i am still taking my very first 3 weeks, bt for the past 3 hours I could only come up with this program and got stuck different places, I don't think this is normal :(
#!/usr/local/bin/perl
use strict;
use warnings;
use Spreadsheet::WriteExcel;
our %information;
open FILE, ">>",'D:\My Code\Records.xls' or die "$!";
binmode FILE;
my $workbook=Spreadsheet::WriteExcel->new(\*FILE);
my @info = ('Name','Age','Specialization');
#adding a worksheet and writing headings
my $worksheet=$workbook->add_worksheet('Personal');
$worksheet -> set_column('A:C',20);
for (my $i=0; $i<=$#info;$i++){
foreach my $key(@info){
$worksheet->write(0,$i,$info[$i]);
}
}
#adding records and initializing a row counter since each value in the
+ hash will have a row
print "How many Records do you want to enter?\n";
my $records =<>;
chomp $records;
my $counter=1;
while($counter<=$records){
my $col_counter=0;
foreach my $key (@info){
print "Enter $key\n";
$information{$key}=<>;
chomp $information{$key};
$worksheet->write($counter, $col_counter, $information
+{$info[$col_counter]}); #indexing @info will give $key
$col_counter++ if ($col_counter<=$#info);
}
$counter++;
}
any feedback on how to improve this programming style, and on how to make this program does what it is supposed to will be greatly appreciated
