CompTIA Tech+ FC0-U71 (V6) Practice Question

A function is a block of code that performs a specific task and can be reused whenever the function is called. Functions promote modularity and make code easier to maintain because logic is written once and invoked as needed. They typically accept input (parameters), contain processing logic, and may return an output. The correct answer reflects these characteristics. The other options describe an array, a single program statement, and a loop, none of which capture the core purpose of a function.
