What does the line // loop function runs over and over again forever describe?

• A. A statement
• B. A single line comment
• C. A function definition
• D. A bowl of cereal

Answer: (B)

Starting with // marks a single-line comment. In many languages, the compiler or interpreter ignores the rest of the line, using it for notes rather than executable code. So the line // loop function runs over and over again forever isn’t actually running a loop; it’s just describing the idea for a human reader. That’s why this is the best choice: it’s conveying information without performing any action in the program. A statement would execute something, a function definition would declare a function, and a bowl of cereal isn’t code at all. Comments help explain behavior without changing how the code runs.
