If you have read the FAQ link then you should not be asking such a
question again and again. Does the link not say undefined behavior ? If
it is undefined then there is no point for me, you or any other Tom,
*** or Harry to try and explain the output.

I would rather suggest you to study on sequence points. After that,
there are a whole lot of other topics which do give you some defined
behavior irrespective of what compilers or platform you are using. It
would prove more beneficial for all if you rather concentrate on those
topics and ask queries on those topics instead.

I wish David's suggestion of killfiles is taken note of.
