Which of the following are good coding style habits?1 pointAdding commentsWriting self-documenting codeCleaning up duplicate code by creating a function that can be reusedUsing single character variable names

The good coding style habits from the options provided are:

1. Adding comments: This is a good habit as it helps others understand what your code is doing, which is especially important when working in a team or when you might have to look back at your code in the future.

2. Writing self-documenting code: This is also a good habit. Self-documenting code is written in a way that's readable and doesn't require much external documentation. It uses clear, descriptive variable and function names, and is organized in a logical way.

3. Cleaning up duplicate code by creating a function that can be reused: This is a good habit because it makes your code more efficient and easier to maintain. If you need to make a change, you only have to do it in one place instead of multiple places.

4. Using single character variable names: This is generally not a good habit. While it might make typing faster, it makes your code harder to read and understand. It's better to use descriptive names that make it clear what the variable is used for.
