Can't access class of a loaded file in the IRB

I have two Ruby files. I am able to access the class of one of the files
but not the other. Here are my two files:

bankaccount.rb:

# http://www.techotopia.com/index.php/Ruby_Object_Oriented_Programming

class BankAccount
   def initialize ()
   end

   def test_method
        puts "The class is working"
   end
end

complex.rb:

class ComplexNumber
  def initialize()
  end
  def a
    @a = 0
  end
  def b
    @b = 0
  end
end

I can create a BankAccount object just fine in the IRB, but when I try
to create a ComplexNumber object I get an error saying "unitialized
constant" even though I entered 'load "complex.rb"' and 'load
"bankaccount.rb"'.

irb(main):008:0> a = BankAccount.new()
=> #<BankAccount:0x2b0fc50>
irb(main):009:0> b = ComplexNumber.new()
NameError: uninitialized constant ComplexNumber
        from (irb):9
        from C:/Ruby193/bin/irb:12:in `<main>'

File name "complex.rb" is used by one of Ruby's library files, and
it's that file that gets loaded. Rename your file or explicitly mark
that you mean the file in current directory: 'load "./complex.rb"'.
