Accessing variables of instances in an array?

Ruby
1

Hi. I want to have an array of instances…

listb = [instance1, instance2, instance3]

I am able to print out the instance…

def printout(an_array)
an_array.each {|item| p item }
end
printout(listb)

How can I print out specific variables for each instance?

eg variables…

name
age

Thanks Jeremy, that does the job. By the way is ‘item’ a keyword?

No, item is not a keyword. You can replace that with any valid variable
name. When you start using other methods that take blocks, you’ll find
that you can use more than one variable within the | … | as well.
Some blocks even take an empty list.
