Question

What is this line of code: void loop()?

1) A statement
2) A single line comment
3) Part of a function definition
4) A banana

Answer 1

The line of code 'void loop()' is part of a function definition in Arduino programming, representing the main loop that runs continuously on the device.

Step-by-step explanation:

The line of code void loop() is part of a function definition. In the context of programming, specifically within the Arduino programming language which is derived from C++, the void loop() function is a fundamental part that continuously runs allowing the device to change and respond. It's where the main logic of the program resides, executing the code within its block over and over again. The way it is written suggests that it defines a function because it follows the syntax:
<return_type> <function_name>(<parameters>).

A statement is an individual instruction like int x = 0;, a single line comment would be something preceded by // explaining the code, and a banana is, of course, a fruit and not related to programming.
