hi,
As I was programming i got again to one thing i alwas needed to have...
especialy when write something fast or debug some result... words comes
about for/foreach and accessing the current-index of the array I'm working
with .... i.e.
say I have two arrays @a and @b and want to print them (also say they are
connected in some way so I want to see them both). In case of one array I
write :
print "$_\n" for @a;
fast, simple, good....but in my case I have to write something like this :
for ($i = 0; $i < scalar @a; $i++) {
print "$a[$i] : $b[$i]\n"
};
I've go tired of typing :"), but if I had current index-iterator ( say under
$i just as example) at hand the way I have $_ i can just type :
print "$_ : $b[$i]\n" for @a;
OR
print "$a[$i] : $b[$i]\n" for @a;
isn't that cute :") ... the same count for list in $i I just get current
position in the list. (we can also use "pos" in some way!!!)
print "$_ : $a[$i] : $b[$i]\n" for (qw(val1 val2 val3));
I need it very often.:")
don't bother if the lenght of both arrays are different.... when u use it, u
know what u are doing...
