+In C++, the ternary operator @code{?:} is available. @code{a?b:c}, where
+@code{b} and @code{c} are vectors of the same type and @code{a} is an
+integer vector of the same size and number of elements as @code{b} and
+@code{c}
Why "same size and number of elements" in the above? What is the
difference between these two?
(on x86_64)
A vector of 4 int and a vector of 4 long have the same number of elements
but not the same size.
A vector of 8 int and a vector of 4 long have the same size but not the
same number of elements.
For semantics, we want the same number of elements. To match the hardware,
we want the same size.
