What does this code mean?

Question

I don’t understand what the third line does. What is it? What do the ? and : do? Is it some kind of shorthand way of an if statement?

x=0
y=1
puts x==y ? y : (x ? 2 : 3)
#answer is 2

Answer 1

puts (x == y ? y : (x ? 2 : 3))
x == y : false, so the ternary expression has (x ? 2 : 3) as a value
x is 0, which is true in Ruby, so the value of the ternary expression is 2

Answer 2

condition ? if_true : if_false
is a ternary operator
To know the value of it, your computer evaluate the condition. If it is true, then the value is what is between '?' and ':', else it is what is after ':'
