Hello everyone, I try to build an easy quiz to learn how to use the basics of ruby but i struggle with the \n.
I coded that :
print "Please enter your name: "
name = gets
puts "Hello\s#{name}"
print "Do you want to answer my quiz ? : "
participation = gets
string = "#{participation}? That's cool !"
puts string
My problem is, when it prints string = "#{participation}! That's cool!", it prints it as that :
Yes
! That's cool !
Whereas, i would like it to be printed as :
Yes ! That's cool !
Could someone explain me why everything i put after {participation} go to a new line ?
I really thank you in advance, Nicolas

It is very common whitespace issues in Ruby that pushing invisible spaces to the next lines, you can ALWAYS use this "chomp" string after gets method to get rid of it, therefore every other languages has different kind of whitespaces and some issues but there are a lot of ways to do it better.
Let's try this: "gets.chomp" .
print "Please enter your name: "
name = gets.chomp
puts "Hello #{name}"
print "Do you want to answer my quiz? "
participation = gets.chomp
string = "#{participation}? That's cool!"
puts string
More details - chomp string

Thanks for your answer. If i've well understood, the program understand "Yes + enter" when we type on our keyboard. It works with the chomp !
Thank you, Nicolas

Courses Plus Student 40,065 PointsYeah, have you thought about if someone type to say "no"?
print "Please enter your name: "
name = gets.chomp
puts "Hello #{name}"
print "Do you want to answer my quiz? (yes/no): "
participation = gets.chomp
if participation == "yes"
puts "#{participation}? That's cool!"
elsif participation == "no"
puts "Have a great day, maybe next time!"
else
puts "I'm sorry. I did not get your answer. Please try again."
end
Hope that helps. :-)
