What is function overloading in Ruby?

Function overloading allows multiple methods with the same name but different parameters. However, Ruby does not support it natively.

Can you give me an example of function overloading in Ruby?

Sure! You can simulate it by using default parameters or variable arguments. For instance:

class Example
  def display(value)
    puts "Value: #{value}"
  end

  def display(value1, value2)
    puts "Values: #{value1} and #{value2}"
  end
end

This will raise an error, but you can use default values to achieve similar functionality.

What are default parameters in Ruby?

Default parameters allow you to define a method with default values for its parameters, making them optional.

Can you show me how to use default parameters?

Absolutely! Here's an example:

class Example
  def greet(name = "Guest")
    puts "Hello, #{name}!"
  end
end

example = Example.new
example.greet # Outputs: Hello, Guest!
example.greet("Alice") # Outputs: Hello, Alice!"
