Is there some sort of ternary operator in Ruby like the one in C++?
eg.
greaterThanFive = (x > 5) ? “yes” : “no”;

Yes:
greaterThanFive = (x > 5) ? “yes” : “no”

Yes, to my newbie-knowledge it is borrowed from C: condition? expr1 : expr2
i.e.,
print "This page has been viewed “, counter, " time”
print (counter == 1) ? “” : “s”

Yup. You don’t need it though, because in Ruby, the if statement returns a value, eg:
greaterThanFive = if x > 5 then “yes” else “no” end
The ternary operator is mainly good for obfuscation, eg:
class Fixnum; def ?;??end end
puts ??.?? ??:?:
