I have one txt-file with six rows and each row contains seven numbers seperated with whitespaces.
I want to:
Compare one array with seven numbers with each row of numbers in the txt-file.
I have managed to compare one array with another with seven numbers (fairly easy), the problem is that i can't figure out how to create six different arrays with the numbers with the rows in the txt-file and then compare them with a single array. I've used qw() to create the array so the values are in fact strings.
Code:
open(FILE, "numfile.txt") || die $!;
my @rows = <FILE>;
I understand that the array @rows now contains six elements and each element is a string with seven numbers seperated with whitespaces.
Is there a way to loop through the @rows array and split the strings into seven different values, populate six arrays with these values and then compare them with an independent array?
Thanks!
hello ,
so you have one array of numbers to compare with all the rows if I am not mistaken.
So here is a start
Code:
#/usr/local/bin/perl -w
open(FILE,"<your_file.txt") or die($!);
while(<FILE>){
split(/\s+/);
##not compare your arrary with @_ by using accessing members $_[0],$_[1]..... .. etc. ###

alzabo::runtime::joincursor
Alzabo::Runtime::JoinCursor(3pm) User Contributed Perl Documentation Alzabo::Runtime::JoinCursor(3pm)NAME
Alzabo::Runtime::JoinCursor - Cursor that returns arrays of "Alzabo::Runtime::Row" objects
SYNOPSIS
use Alzabo::Runtime::JoinCursor;
my $cursor = $schema->join( tables => [ $foo, $bar ],
where => [ $foo->column('foo_id'), '=', 1 ] );
while ( my @rows = $cursor->next )
{
print $rows[0]->select('foo'), "
";
print $rows[1]->select('bar'), "
";
}
DESCRIPTION
Objects in this class are used to return arrays of Alzabo::Runtime::Row objects when requested. The cursor does not preload objects but
rather creates them on demand, which is much more efficient. For more details on the rational please see the RATIONALE FOR CURSORS section
in Alzabo::Design.
INHERITS FROM
"Alzabo::Runtime::Cursor"
METHODS
next
Returns the next array of "Alzabo::Runtime::Row" objects or an empty list if no more are available.
If an individual row could not be fetched, then the array may contain some "undef" values. For outer joins, this is normal behavior, but
for regular joins, this probably indicates a data error.
all_rows
This method fetches all the rows available from the current point onwards. This means that if there are five set of rows that will be
returned when the object is created and you call "next()" twice, calling "all_rows()" after it will only return three sets.
The return value is an array of array references. Each of these references represents a single set of rows as they would be returned from
the "next" method.
reset
Resets the cursor so that the next "next()" call will return the first row of the set.
count
Returns the number of rowsets returned by the cursor so far.
next_as_hash
Returns the next rows in a hash, where the hash keys are the table names and the hash values are the row object. If a table has been
included in the join via an outer join, then it is only included in the hash if there is a row for that table.
