Hi, I was just exploring the loop function with gets.chomp syntax, but it seems like the gets.chomp input doesn’t work in the loop function. Is there a reason for this?

This is how my code looks like:

print "Tell me your age."
age = Integer(gets.chomp)

loop do
  age += 1
  print "#{age}"
  break if age <= 30
end

Instead of looping up to 30, it only looped up to 26. Why is it so? Is there another way to make this work?

Hello :slight_smile:

I think that the problem is caused by this condition.

Let’s say that I am 26 years old, age = 26. Now we get into the loop block, age += 1 results in age = 26 + 1 = 27. In the next line of the code 27 is printed out to the console. And now if 26 <= 30 (which is true) we break and the loop stops.

And if my input is 55 then we have an infinite loop.


The condition should be probably changed to age >= 30.

Hello, I was just wondering why the example code block uses print "#{i}" when print i seems like it would do the same thing
