Which is better too many comments or too few comments?

Too many comments may be bad, if the comments do not add information about how the code works. Extra comments do not hurt anything. But too few comments is much worse, because even the author of some code cannot really understand it completely after a few months.

However, having good comments which explain why the code is doing something a certain way can (and usually is) important for maintenance.

Why is it important that code be well commented and well formatted?

So, the well commented functions/logics are helpful to other programmers to understand the code better. They can easily understand the logic behind solving any problem. If you see/edit code later, comments may help you to memorize your logic that you have written while writing that code.

Why do we use functions in programming?

This example highlights the two most important reasons that C programmers use functions. The first reason is reusability.
