How do I use the conditional operator (? :) in Ruby?

Question

How is the conditional operator (? :) used in Ruby?

For example, is this correct?

<% question = question.size > 20 ? question.ques         


        

Answer 1

A simple example where the operator checks if player's id is 1 and sets enemy id depending on the result

player_id=1
....
player_id==1? enemy_id=2 : enemy_id=1
# => enemy=2

And I found a post about to the topic which seems pretty helpful.
