Answer
Use 'printf()' with '%.2f'. Frame the concept in practical terms so you can explain it during interview discussion.
To ensure prices appear with two decimal places, use 'printf()' with '%.2f'. This keeps your e-commerce app's output consistent, showing prices like 19.90 instead of 19.9, which enhances readability.
