Functions are well-organized, non-reusable code segments used to implement a single, or associated Function.

Options

• ATrue
• BFalse

• B
  80% (28)

Explanation

B (False) is correct because the statement contains a critical contradiction: functions are explicitly designed to be reusable. Reusability is one of their core purposes - you define a function once and call it as many times as needed, from anywhere in your program. The statement is otherwise partially accurate (functions are well-organized and typically handle a single responsibility), but "non-reusable" fundamentally mischaracterizes what functions are.

Why A (True) is wrong: Accepting the statement as true would mean agreeing that functions cannot be reused, which directly contradicts how functions work in virtually every programming language.

Memory tip: Think of a function like a recipe card - you write it once and follow it as many times as you want. If it were non-reusable, you'd have to rewrite the recipe from scratch every meal. The whole point of a function is to avoid repeating yourself (DRY principle: Don't Repeat Yourself).
