How do variable names affect code readability?

Variable names play a crucial role in code readability. They should be descriptive enough to convey the purpose of the variable, making it easier for others (and yourself) to understand the code later.

Can you give me an example of good and bad variable names?

Sure! A good variable name might be totalPrice, which clearly indicates what it holds. A bad name could be x, which is vague and doesn't provide any context.

What are some best practices for naming variables?

Some best practices include using meaningful names, following a consistent naming convention (like camelCase or snake_case), and avoiding abbreviations that aren't widely understood.

Does the length of a variable name matter?

Yes, the length can matter. While names should be descriptive, overly long names can make code cumbersome. Aim for a balance between clarity and brevity.
