Using OR in an IF statement

Hi,

I'm trying to make a shortcut for "reverse" and "uppercase" by allowing the user to type "r" and "u" respectively. What would be the correct way of implementing this because the code below does not seem to work.

Thanks!

print "Enter name: "
name = gets.chomp.capitalize

if name == "Andrew"
  puts "That's my name, too!"
else
  puts "Hi #{name}!"
end

print "Modify your name (reverse or uppercase): "
response = gets.chomp.downcase

if response == ("reverse" || "r")
  puts "Your name in reverse is: #{name.reverse}"
elsif response == ("uppercase" || "u")
  puts "YOUR NAME IS: #{name.upcase}!"
elsif response == "both"
  puts "Your name in reverse and uppercase is: #{name.reverse.upcase}!"
else
  puts "That wasn't one of the options, learn to read!"
end

Okay, so it touches on this a few lessons later. See the code below for the answer.

Using IF

print "Enter name: "
name = gets.chomp.capitalize

if name == "Andrew"
  puts "That's my name, too!"
else
  puts "Hi #{name}!"
end

print "Modify your name (reverse or uppercase): "
response = gets.chomp.downcase

if (response == "reverse") || (response == "r")
    puts "Your name in reverse is: #{name.reverse}"
elsif (response == "uppercase") || (response == "u")
    puts "YOUR NAME IS: #{name.upcase}!"
elsif (response == "both")
    puts "Your name in reverse and uppercase is: #{name.reverse.upcase}!"
else
  puts "That wasn't one of the options, learn to read!"
end

Using CASE

print "Enter name: "
name = gets.chomp.capitalize

if name == "Andrew"
  puts "That's my name, too!"
else
  puts "Hi #{name}!"
end

print "Modify your name (reverse or uppercase): "
response = gets.chomp.downcase

case response 
  when "reverse", "r"
    puts "Your name in reverse is: #{name.reverse}"
  when "uppercase", "u"
    puts "YOUR NAME IS: #{name.upcase}!"
  when "both"
    puts "Your name in reverse and uppercase is: #{name.reverse.upcase}!"
else
  puts "That wasn't one of the options, learn to read!"
end
