G'day rammohan,

The title has "how many elements are present in an array" and the text has "how many arrays are present in my array".

You do not show any arrays!

As already pointed out to you on multiple occasions (in both SoPW and the CB), please read perlintro. Amongst other basic information, this will show you how to construct an array and determine the number of elements. It also provides links to further, relevant material.
