Variables and Scope Exercises

1. For the following script, draw the variables / pointers and how they interact with objects in memory. Refer to the video in the reading for help!

    a = 5
    b = a
    c = b * a
    a = 6
   
    puts a
    puts b
    puts c
   

2. Draw the pointers for the following script. Use an asterisk to represent variables of the same name, but different scope. (ex a*)

    def multiply(a, b)
      c = a * b
      return c
    end
   
    a = 5
    c = a
    b = multiply(a, c)
   
    puts b
