Question printing array contents after "push" of elements gives a different output in PERL


hi,

i have a doubt in printing the contents of an array after doing
"push" on it.
The question goes as follows.


@arr=qw(1 2 3 4 5);
print @arr;
print "@arr";

The above yields 1 2 3 4 5
1 2 3 4 5 which is nothing but contents of the array.

suppose,
@arr=qw(1 2 3 4 5);
@arr=push(@arr,"a");

print @arr;
print "@arr";


The above yields the array count with o/p as 6 6 .

Could somebody tell why is it so.
Also tell me how to get the contents of the array?

I tried opening a foreach loop for the array and tried printing element by element.
This again yielded the array count than its contents.
Ur explanation is highly appreciated.


Thanks
~ gaynut

Code:
man perlfunc
push returns the number of elements in the array following the completed "push".
