What will be the values of …

Consider the following code:

class A
  def self.a(b)
    if b > 0
      b * b
    end
  end
end

What will be the values of:

• var1 = A.a(0)
• var2 = A.a(2)

• var1 will be equal to nil
• var2 will be equal to 4

A conditional statement in Ruby is an expression that returns nil if the conditional is false. Ruby methods return the last expression in the method body.
