first of all my apologies to all,for asking a question that may be very silly,but i am not ashamed to tell that i duuno the concept about this... :-(,so i am ready to show my ignorance and not become ignorant my whole life...anyway following is the question,and please can some one define it or give some good link about it.It will be really helpful for me.

Melodrama does not really help. Why is it that Indians on any mailing list use such words? Its a mailing list not an amateur dramatics forum.

1) Where in memory exactly auto,static and extern(global) variables are

stored..?

2) Detail explanation of the memory model of a C program.

Have you heard of GDB?

To answer question 1 and 2 please refer here(there is not a more eloquent answer ANYWHERE else) :

http://www.dirac.org/linux/gdb/02a-Memory_Layout_And_The_Stack.php#memorylay...

If you want a GDB tutorial :

I am confused where in memory these variables are stored and also what are

the stages in memory during compilation.. It will be very helpful for me,if someone guide me.

What surprises me is that you have not explored GDB earlier. i remember you talking about memory programming in an earlier mail curious how you manage debug those programs.

i remember my first encounter happened when i saw the ``immortal words" :

Segmentation Fault: core dumped
