use of an unspecified value, or other behavior where this International Standard provides two or more possibilities and imposes no further requirements on which is chosen in any instance
This sentence is in C99 which is the official documentation written by ANSI about a programming language. So I think this sentence won't wrong. But on which is chosen in any instance
looks awkward. I have known when a preposition relative pronoun is used, following sentence should be a full(complete) sentence. But a subject is omitted.
How should I interpret this sentence and is it grammatically correct?
is chosen in any instance
should originally be a full sentence. we have different point of view. And now I understand that noun phrase regardless of this topic. Thanks for your comment.the hotel at which I stayed
, you saidthe hotel at which I stayed
is a sentence. And I saidI stayed
is a sentence. This is the difference between us.
