I have an articles where each article contains 2 or more articles nested. I have used threading concept to thread it. The values of the article is not in sequential. Suppose first article has 2 articles within it and second article has 6 articles. The value of the article is Count of articles_id displays 2,6,etc. $i=0; for my $id(@article_id){ print $i; $i++; } output will be 1,2,1,2,3,4,5,6 The for loop initializes the value as 0 for each article. How to store the value of last value of the varible when exits from each iteration. So that the value is 1,2,3,4,5,6,7,8.
