0.I read that ANSI C rules for variable declaration says that one must

declare

quoted

the variables at the beginning of any scope block.
 C99 onwards we are allowed to declare variables as & how required.

1.NOW, my doubt is what happens in the actual "practical/real-world"

codes that

quoted

are written in industry.
Do everyone *strictly* follow the ANSI C rules & declare the variables

at the

quoted

beginning of the scope ?

Yes, I do.

2.Also , why are we still following that old rule ? Is it so that old

codes of

quoted

70s can be used with new codes ?

Because I like it. And I think it's better sometimes, for example,
variable declaration you mentioned, it's eaiser to trace all variables
by following the ANSI C standard.

ANSI C codes can be used with any modern compiler. And you can mix it
with other newer standards.

3.There must be some standard that all of us need to follow , so what

are they

quoted

?

May be the standards followed by most people are gnu89(ANSI C with GCC
extensions) and C99.

Thanks for the reply Adam !

PS, this is kind of out of topic in a kernel mail-list.

Yeah , even I was sort of confused whether to aks this here or not.
Will take next time onwards :)
