Re: Increment by 2 and by 1 in same loop.

Like this:

my $x=0;
my $size=5;
for( my $i=0; $i<$size; $i+=2,$x++ ) {
        print "$i:$x\n";
}

my $x=0;
my $size=5;
for( my $i=0; $i<$size; $i+=2 ) {
        print "$i:",$x++,"\n";

It's also possible to define (and initialize, if needed) two (or more) lexical loop variables entirely locally: `for (my ($i, $n) = (1, 2); $i < $limit; $i += 2, ++$n) { do_something_with($i, $n); }` [download]	[reply] [d/l]
