Can you give me some examples of Ruby methods?

Can you give me some examples of Ruby methods?

Sure! In Ruby, methods are defined using the def keyword. For example, here's a simple method that adds two numbers:

def add(a, b)
  a + b
end

You can call this method like this: add(2, 3) which will return 5.

What about methods with default parameters?

Great question! You can define default parameters in Ruby methods. For example:

def greet(name, greeting = 'Hello')
  "#{greeting}, #{name}!"
end

If you call greet('Alice'), it will return Hello, Alice!, and if you call greet('Bob', 'Hi'), it will return Hi, Bob!.

Can you show me an example of a method that returns multiple values?

Absolutely! In Ruby, you can return multiple values using an array or a hash. Here's an example using an array:

def coordinates
  [10, 20]
end

You can call it like this:

x, y = coordinates

Now x will be 10 and y will be 20.

What about method overloading?

Ruby doesn't support method overloading in the traditional sense, but you can achieve similar functionality using variable arguments. For example:

def display(*args)
  args.each { |arg| puts arg }
end

You can call display('Hello', 'World') and it will print both arguments.
