OK OK I was temporarily blinded by my own cleverness ;P

What I meant was that with an OR statement once you have a true outcome
nothing can change that fact, what I did not take into account is that
some compilers might actually evaluate all the statements and then
calculate the result - which in essence should not change the outcome
but in my book are a seriously inefficient way of doing it.

;-)

Cheers

Yes, the question asked is related to the functions/statements inside
the expressions that have side effects, and whether it can be assumed to
be both executed or not.

The problem is: "How does the compiler see it?"
