Would this be considered bad coding style? Motivate your answer.

Can you guarentee what will be assigned to what if x==0 or x==1? If not, you
have been answered.

Also x++ is a rvalue, not an lvalue, so even if ?: has been extended to lvalues,
this won't work.

OK, I apparently need parentheses around `y *= 2' so it should read

(x == 0)? x++: (y *= 2);
