Im using pre C-ansi book.Should I purchase newer ...
 

hi

Since Im learning C from book(almost finished reading it) written prior to C ansi standard,I was wondering if I should purchase a new book?

I realise function definitions have changed,but what about other things?

Are there only few changes or are there lots of changes,and
so buying newer book would be a must?

bye

C is rather simple language, that's why I think you don't need to buy a newer book. Just when writing first code use strict ansi compiliance (in gcc it's -ansi switch). That way you'll learn what's changed fast.
It's hard to say what changed since your book was released without knowing its title and print date. :)

hi

I wrote an old style function and using $cc -ansi hello.c command it should report error,but it didn't report any errors! Is this type of syntax ansi supported?

first(a)
int a;
{...}

Why is compiler ignoring ansi option?

thank you

PS:Im learning from C programming language(Brian W Kernighan),edition 1983

It is better to follow the ansi-c version of the book, that is the second edition of the book named The C Programming Language Kernighan & Ritchie

If I can get compiler to accept only ansi-c compliant code,then I think will be ok

K&R is the only book when it comes to learning C. Nothing compares to it.

well,from what I hear second edition is THE book:D,and ffirst edition was the book before ansi-c came along

It shouldn't even without -ansi. Could you paste the whole code you're trying?
