Answer Posted / siva
In additon to the Abhinav answer, Once value assigned to
mapping parameter, it can not be change as per login in
mapping.
Where as if you define as mapping variable, it can be
initialized, can be changed the value as per logic in
mapping and even it can be held as persistent to use the
same value in running session next time.
I think you understand this..
