What are the best practices for commenting in C++?

When commenting in C++, it's important to be clear and concise. Use comments to explain why code exists, not just what it does.

Can you give me examples of good comments?

Sure! For instance, instead of saying // Increment i, you could say // Increment i to track the number of iterations in the loop.

Should I comment every line of code?

No, avoid over-commenting. Focus on complex logic or important decisions rather than obvious code.

What about formatting comments?

Use consistent formatting for comments. For example, start with a capital letter and end with a period for full sentences.
