How can i get an input from user and then use it in my if statement

Question

Like if i want to ask a user how old is he? He inputs 19
My if statement says if age>18 puts "welcome"
Esle puts "too young"

Answer 1

puts 'what\'s your age'

age = gets.chomp.to_i

if age >= 18

puts 'welcome !'

else

puts 'You shouldn\'t be watching this'

end

Answer 2

to_i is used to convert a string (which is the user's input in this case) to an integer.
if you don't use it in this scenario you'll get an error.
well in a regular console it would have pirnted "what's your age" first, then asked the user to enter his age, then displayed the answer ( welcome or too young). Sololearn s compiler works a bit differently​. If u don't want "what's your age", you could simply delete the first line.

Answer 3

I run it and in output it writes what's your age
And what does to_i means?

Answer 4

age=input("your age")

Answer 5

What is the output of this code?
x = 5
unless x < 8
x += 3
else
x += 2
end
puts x
