What do you call a block of code that you can call repeatedly and that returns a value?

• A. Parameter
• B. Loop
• C. Function
• D. For Loop

Answer: (C)

A function is a block of code you can call repeatedly and that returns a value. You define it once, and you can reuse it with different inputs to get consistent results. The return statement sends a value back to the place where the function was called, which is what makes the function capable of contributing a value to the rest of the program rather than just performing actions. A parameter is part of the function's interface—the variable in the function definition that receives the input when you call the function. It’s not the reusable block itself, just the way you supply data to it. A loop, including a for loop, focuses on repeating a set of instructions. It may be used inside a function, but by itself a loop isn’t the thing you call to obtain a value back from a single operation. The function is the construct that provides a value to the caller after performing computations.
