What is the difference between default values and required parameters in programming?
An example of an AI chatbot conversation about default values vs required parameters in programming.
What is the difference between default values and required parameters in programming?
Default values are optional values assigned to parameters if no argument is provided, while required parameters must be supplied.
Can you give me an example of each?
Sure! In Python, a function like def greet(name='Guest'): has a default value. If you call greet(), it uses 'Guest'. But def add(a, b): requires both a and b.
What happens if I don't provide a required parameter?
If you don't provide a required parameter, the program will raise an error, indicating that the argument is missing.
Are there any programming languages that handle this differently?
Yes, some languages like JavaScript allow for more flexible parameter handling, including default parameters and rest parameters.
