A = X > Y ? X : Y

Why not just use the max method?
a = max(x,y)
It is more obvious what the idea is, and has the advantage of allowing for
more than two variables:
a = max(x,y,z)
The opposite function min is also available.
I realize that the intent may be to use the test for something different
than less than / greater than, but for readability I would suggest a
multi-line if..else statement. We have to maintain the code we write and
most of us have to remember about the ? operation in C and take extra time.

Brad's example is incorrect, and is not in the FAQ. Cliff's example
is the correct one, although I agree with him that it is not to be
People ought to look at the FAQ when they talk about it. They also
ought to look in it if they fear that their questions have already
been asked. ;-)
The entry at
explains this quite well, and gives the correct expression.
