An example of an AI chatbot conversation about default parameters in Ruby.
What are default parameters in Ruby?
Default parameters in Ruby allow you to set default values for method arguments. If no argument is provided, the default value is used.
Can you give me an example of how to use default parameters?
Sure! Here's a simple example: def greet(name='Guest') puts "Hello, #{name}!" end. If you call greet(), it will output 'Hello, Guest!'.
What happens if I provide an argument when calling the method?
If you provide an argument, it will override the default value. For example, greet('Alice') will output 'Hello, Alice!'.
Are there any limitations to using default parameters?
One limitation is that default parameters must be placed at the end of the parameter list. You can't have required parameters after default ones.
