What are the differences between optional and required parameters?
An example of an AI chatbot conversation about the differences between optional and required parameters.
What are the differences between optional and required parameters?
Required parameters are necessary for a function to execute, while optional parameters can be omitted.
Can you give me an example of each?
Sure! In a function that calculates the area of a rectangle, width and height are required parameters. An optional parameter could be a unit of measurement.
What happens if I don't provide a required parameter?
If you don't provide a required parameter, the function will typically throw an error or fail to execute.
Are there any programming languages that handle this differently?
Yes, some languages allow default values for optional parameters, while others may have stricter rules.
