Hi, is there a conditional operator in Ruby like the ? in C/C#, ie

x = y == nil ? 0 : 1

I know you can do

x = if (y == nil) then 0 else 1 end

Just wondering if the more compact is possible in Ruby.  

Thanks!

you can use the ? in ruby as in C

x = y == nil ? 0 : 1

Huh - so I guess the above would also be

x = y.nil? ? 0 : 1

Cool - I feel like I fool for not trying it - I ASSumed since a lot of the methods ended in ?  it wouldn't also be an operator.

Thanks again.

yep,
x = y.nil? ? 0 : 1
would be the nicer, more ruby-like form
