Problem with If Statement in Ruby Program

Question

I'm super beginner to ruby, but for some reason my if statement isn't working. Whenever the name 'Cristina' is entered, the program continues to print "Hello there".

def Cus_free_makers_eg1heChallenge(str)
  str = gets
  if str == "Cristina"
    print "Hello Cristina!"
  else
    print "Hello there!"
  end
  return str
end

Change it to if str == "Christina\n". After the gets, the string will have a terminating newline. More sensible would be maybe a if /Christina/ =~ str. — user1934428

Add strip to remove newline:

str = gets.strip
if str == "Cristina" 
  print "Hello Cristina!"
else
  print "Hello there!"
end

Still doesn't seem to work. I added an elsif statement also, but that doesn't work either..

This does work. I think chomp is the preferred way - but both work in this case.

This works:

str = gets.chomp

if str == "Cristina"
  print "Hello Christina!"
else
  print "Hello there!"
end

str

Ruby gets statement is usually ended with chomp or chomp! to -- you guessed it -- "chomp" aka remove the trailing newline and carriage characters. More info in Ruby doc: https://docs.ruby-lang.org/en/3.0.0/String.html#method-i-chomp

I also took the opportunity to remove return and also the trailing end as both aren't necessary.
