20,629 PointsCase statement using and / or operators
I am wondering if CASE statements can also handle && / ||
I have tried and though it runs, it then always goes to the else statement. Since there isn't an actual console error, I am wondering it would thus be possible and I'm just missing something...
print "Enter name: "
name = gets.chomp
if name.upcase == "ERIK"
puts "That's my name, too!"
else
puts "Hi #{name}!"
end
print "Modify Your Name. Type 'uppercase' or 'reverse': "
answer = gets.chomp.upcase
case answer
when "UPPERCASE" || "UPPER" || "UP"
puts "This is your name in uppercase: #{name.upcase}"
when "REVERSE" || "REV"
puts "This is your name backwards: #{name.reverse}"
when "BOTH"
puts "This is your name both backwards and in uppercase: #{name.upcase.reverse}"
else
puts "Ok, maybe later"
end

18,425 PointsI am by no means a Ruby expert, but it does not appear that the CASE statement accepts || operators. See http://ruby-doc.org/docs/keywords/1.9/Object.html#method-i-case for more info. I did notice that the script ran perfectly except for the OR statements.

In a case statement, a "," is the equivalent of "||" in an if statement.
Hope this could give some help :)
