As you all might already know that an array is known
as 'Repeating Groups' because of there nature, it means
that it is a group of data-items, 01 level is used to
define group level variable only (not the groups directly),
so data-items of group needs to be defined under 01 level
(group level) variable only, we can not declare them on 01
level directly.
