User Defined Functions

User Defined Functions are custom tools created by programmers to perform specific tasks within a computer program. Think of them as personalized recipes: once written, they can be reused whenever needed, saving time and reducing errors. Instead of rewriting the same code multiple times, a programmer can call this function, which then executes the task efficiently. This makes programs more organized, easier to understand, and maintainable. Essentially, user defined functions help tailor the program’s behavior to particular needs, providing flexibility and structure to software development.
