How to tell the last iteration in a foreach loop?

meili100

The last element will also be followed by a ":" which is not what I want. Is there a way to tell when foreach loops to its last round, so that I can skip printing the last ":"? Thanks!

First, please use code tags, they are required.

Second, can you provide a sample of the data so we can see what you are talking about?

for example assume i have an array i.e,
Above for loop we r excluding last element to print;

That's because you have i<$#a - use i<=$#a instead.

Better yet, use a foreach loop:

for example assume i have an array i.e,

Expand|Select|Wrap|Line Numbers

1. my @a = (1,2,3,4,5,6);
2.  
3. for(my $i = 0;$i<$#a;$i++) {
4.          print $a[$i];
5. }
6.  

Above for loop we r excluding last element to print;

Next time post a new thread.
