[lug] Re: Reagarding structures

Adam,

It is working absolutely fine when I decalred and defined
outside the main.
I am having certain doubts about this program..........if it is
possible could U clarify me?
I declared and defined the struct varaible in inside the main,
If I passing from the main why I am unable to access it ?is
there any specific reason
