Certain individuals might find themselves pondering: what is the rationale behind incorporating comments into our codebase? What precise role does it fulfil? It is worth noting that comments, in themselves, do not exert any direct influence on the code’s functionality or execution. So why bother? Well, think of coding as writing a recipe for your computer to follow. But imagine if you wrote the recipe, and then later you forgot why you included some ingredients or steps. That’s where comments come in.

Comments are like little reminders you leave in your code. They help you remember why you did certain things, even if time has passed. It’s like leaving yourself helpful notes to understand your own recipe.

Not only that, if you’re working with others, comments help them understand your code too. It’s like sharing your cooking secrets with someone else so they can help you in the kitchen. And just like recipes change over time, code needs updates too. When you need to change something, comments guide you so you don’t mess things up.

So, commenting on your code is like keeping a recipe book that never gets old. It keeps your code tasty and easy to understand, no matter how much time goes by.

Exploring Code Commenter Template

Having grasped the significance of incorporating comments into your code, let’s consider the fate of pre-existing code that you’ve crafted without a clear understanding of the purpose behind certain sections. Picture this: You’re faced with a stack of older code that you never bothered to comment. Now, as you gear up to make edits, you’re left scratching your head over the purpose of certain lines.

  • In the Prompt tab, there are pre-configured messages which provides more information for the AI to learn from.

below are the detailed task steps the AI application follows

Step 1: Identify the programming language.

Step 2: It is crucial to make sure your comments written are properly recognized as comments/annotations in the programming language identified and not interfering with the code functionalities.

Step 3: Write code comments following the best practice rules:

  • Rule 1: Comments should not duplicate the code.

  • Rule 2: Good comments do not excuse unclear code.

  • Rule 3: If you can’t write a clear comment for certain lines and there may be a problem with the code, indicate and explain why the code is unclear in the code comments.

  • Rule 4: Comments should dispel confusion, not cause it.

  • Rule 5: Explain unidiomatic code in comments.

  • Rule 6: Add indication in comments whenever a bug emerges.

  • Rule 7: Use comments to mark incomplete implementations.

Step 4: There are three types of comments: Header Comments for the entire code snippet to explain the overall purpose of this code snippet, Header Comments for individual functions to explain the purpose of the function, and In-line Comments for individual code lines to explain the purpose of this line of code. Both kinds of Header Comments are required. In-line Comments are written only when it is necessary, for example, a line of code worth noting or indications instructed in step 5 and 6.

Step 5: Check again if there is any bugs and improper, not ideal, or incomplete code.

Step 6: Indicate issues you found in step 5 and indicate them as In-line Comment near the problematic code.
