Why are comments important in C++ code?

Why are comments important in C++ code?

Comments in C++ code are crucial for improving readability and maintainability. They help explain complex logic, making it easier for others (or yourself) to understand the code later.

Can you give me an example of a good comment?

Sure! A good comment might explain the purpose of a function, like this: // This function calculates the factorial of a number recursively. This helps anyone reading the code understand its intent.

What happens if I don't use comments?

Without comments, code can become difficult to understand, especially for others who may work on it later. It can lead to confusion and increase the time needed for debugging and maintenance.

Are there any best practices for writing comments?

Yes! Some best practices include being concise, avoiding obvious comments, and updating comments when the code changes. Aim for clarity and relevance.
