Question: 1 / 400

What is a benefit of using user-defined functions?

They automatically optimize performance

They promote code reuse and organization

User-defined functions provide significant advantages in programming, particularly in promoting code reuse and organization. By defining functions, programmers can encapsulate specific tasks or calculations into discrete units. This means that the same code can be reused multiple times throughout a program without needing to rewrite it, reducing redundancy and the potential for errors.

Additionally, organizing code into functions improves readability and maintainability. Each function can be designed to handle a particular aspect of the program, allowing for a clearer structure and making it easier for others (or the original author at a later date) to understand the flow of the program. Overall, user-defined functions enhance the modularity of the code, enabling easier updates and enhancements by allowing programmers to focus on smaller sections of the program independently.
