Hi!

I am trying to understand weather to use c89/c90 or c99 and have come
up with some questions that I would be interested in hearing your
thoughts about:

What is the advantage of writing a program according to c90? Dito for
c99?

What is the disadvantage of asking someone to write a program
according to c90 instead of c99? Dito for "c99 instead of c90"?

What do you recommend when giving programming assignmnts/jobs: "write
the program according to c90" or "write the program according c99"?

As far as I understand the best (best as being most portable) thing is
to write C-programs that comply with c89, c90 and c99.

How are C-compilers "officially certified" to comply with c89, c90 and
c99?

BRs!

I write C programs in the common subset of the two.

Is C90 not a subset of C99?

Not entirely, C99 got rid of implicit int and also implicit function
declarations for instance, and that''s because they were anti-features in
the first place.
