Question

I’m starting to learn Ruby. I read that arguments where passed by reference to a method,
however I don’t understand the difference between these two methods.

def print(text)
   puts text
end

and

def print(*text)
    puts text
end

Using a * means that we are passing a pointer like in C?

Answer 1

The *text is what’s called the splat operator in Ruby. It basically means if you pass multiple arguments to the second print they will get slurped into the single text variable.
