How can I write effective comments on code?

What are some tips for writing effective comments in my code?

Effective comments should be clear, concise, and relevant. Focus on explaining the 'why' behind your code.

Should I comment on every line of code?

No, avoid commenting on every line. Instead, comment on complex logic or important decisions to enhance understanding.

How do I know if my comments are helpful?

Ask for feedback from peers or revisit your code after some time. If the comments still make sense, they're likely helpful.

Can you give an example of a good comment?

Sure! Instead of saying 'increment i', a better comment would be 'increment i to track the number of iterations in the loop'.
