Question

Fill in the blanks to create a method that takes optional parameters and outputs the squares of its parameters:

def sq(_p)
__.each {|_| puts x*x}
end

Answer 1

You can use the asterix (*) in front of a parameter name to get an array of values.

def sq(*p)
p.each {|x| puts x*x}
end

sq(3, 5.6, 42)
