As a professional you may need to do code maintenance and bug fixing also.
There might be instances where some moron has written this kind of code.
Struct address +1 and so on.
if such code is written it is ONLY because fools keep providing
incorrect answers to such questions as "how do I do it?"
So when you go through this sort of code you actually need to know
what the programmer tried to do there,
It is a bad coding practice but in real world you need to know the
bad things if you want to be good.
I will give you an example :
I was going through mplayer code. The code was doing some protocol handling.
To get into the data part he did a base address + sizeof(header struct).
He was getting the data in
base address + 31
When I took the same code and used it somewhere else I was getting
base address + 32 and i was losing the first byte of data field..
He had pragma packing enabled and my compiler did not support pragma
packing and I spent an hour finding this problem as the code base was huge.
So here in c-prog , we actually need to educate people about the
pitfalls of this kind of bad coding practice with examples.
They are asking because they don't know, it's as simple as that.
then don't take offense when I yell "DON'T DO THAT!!"
Best ,

The structure Name always points to the first element of the structure.
Orgin + 0 == Orgin.ch it is True
but Orgin +1, Orgin+2 not points to the next elements.
Why?
you still haven't answered MY question.
Why do you think you need to do this?

any body tell me how to access the structure elements without
using the elements name.
short answer: no.longer answer: portably? definitely not.
now for my question. Why do you think you need to do this?
(e.g) typedef struct
{ char *ch; int id;
float salary; } Base; Base orgin; orgin + 0 point to the
first element of Base ( ch )orgin +1 point to second element
of Base (id)orgin + 2 point to Third element of Base (
salary) Is it possible to access the elements like this , if yes
please let me to know Thanks&Regards,Selvan.
