No. It may or may not have been what you /meant/, but what you /said/ 
was: "unary operators such as sizeof have a higher precedence than
the ternary operator, so sizeof is evaluated before ?:" and "Precedence 
rules require the unary operator be evaluated before the ternary operator."

They don't. Precedence doesn't actually exist as a concept within the C 
definition, but it is nevertheless a handy and, as far as I'm aware, 
wholly accurate rule of thumb that we can follow when writing code. But 
we confuse precedence and evaluation order at our peril.

In the current case, sizeof x ? B : C; the operand of sizeof is not 
evaluated at all (if x had had the syntax of a function call, for 
example, that function wouldn't have been called).

The grammar for which precedence is a handy shortcut binds x to sizeof. 
So it is /as if/ (sizeof x) ? B : C had been written.

The result of the sizeof is of course required before the conditional 
operator can know which of B and C to evaluate (if they were functions 
with side effects, which function to call). In fact, the ? can be 
thought of as representing a sequence point, because ?: can't decide 
between whether to evaluate B or C (for it must evaluate one and only 
one of them) until it knows what (sizeof x) is.

But this is nothing to do with precedence. Precedence dictates only 
which operands bind to which operators. Thus, precedence tells us that 
the syntax tree is constructed as follows:

      +--------?:---------+
      |         |         |
   sizeof       B         C
      |
      x

In this particular case, of course, sizeof doesn't evaluate its operand 
and so this construct has /nothing to say/ on whether precedence governs 
evaluation order. Indeed, I have already presented code which shows that 
it does not.

Indeed.

Then you are mistaken again.

No, the grammar rules here. Precedence tells us that it is x, not x?B:C, 
that is an operand of sizeof. And that's /all/ it tells us. Yes, sizeof 
x has to be evaluated before ?: can be evaluated, but *all* operators 
need to evaluate all their operands (except, perhaps ironically, in the 
cases of sizeof and ?:) before they can yield a result. Precedence does 
not determine the order in which this is done. It only determines which 
results of evaluation belong to which operators.

yielded, not returned.
