I was happily coding my way through a program when out of the blue there came a glitch...

I believe they are 2 ways to write a for / foreach loop :

• for (my $i=0;$i<@array;$i++)
  {
     $array[$i] = 3; # dummy value
     # do your stuff, $i being the counter
  }
  [download]

• foreach (0..@array)
  { 
     $array[$_] = 3;
     # do your stuff, $_ being the counter
  }
  [download]

However, in my bit of code, the second and third methods only work fine with the first element and fails with the others.

It then occured to me that foreach (0..@array) seemingly went from 0 to to the size of the array. I then reread some array info and realized that was it ! I'm quite bashful now... It's so obvious that an array name returns the actual array size...

Isn't there yet another way, something like

foreach(@array)
{
   # use $_ as counter
   # do your stuff
}
[download]

Thanks for your insight, David.
