What is the role of comments in programming code?

• A. To enhance the execution speed of the code
• B. To improve the aesthetic layout of the code
• C. To annotate code for better understanding by developers
• D. To provide error messages to users

Answer: (C)

Comments in programming code serve as annotations that help developers understand the logic and functionality of the code. They are particularly important for enhancing readability, allowing anyone who reads the code—including the original author at a later date or other team members—to grasp the purpose of specific sections quickly. Comments can clarify complex logic, describe the intention behind certain decisions, or provide context that is not immediately obvious from the code itself. Comments do not influence the execution speed of the code, meaning they do not help the program run faster. They also do not contribute to the code's aesthetics in a way that would affect its functionality. Instead, their primary purpose is to communicate information to developers without impacting the execution or performance of the program. Additionally, comments are not designed to provide error messages to users; rather, they are used internally for developers to enhance their understanding and collaboration during the coding process.
