this is a doubt i came up with when i was tryin to pop out the entire contents of an array..
 
    foreach(@conseq)
    {
        pop @conseq;
     }

this code dint work properly.. i was still gettin some elements in the array..  But..
   
    foeach(0..scalar(@conseq))
    {
       pop(@conseq);
     }

  This code cleared out the entire array.. Any explanation why this is so..??



 


Yes, it's because the first piece of code sets up a temporary list for perl to traverse and doesn't keep going back to the original each time.  Whther or not it behaves in this way doesn't matter in the second case as you're using a count.
