Question: 1 / 565

Which guideline should be followed when creating preprocessor macros to reduce bugs?

Use the inline keyword before the macro.

Capitalize all characters in the macro name.

Capitalizing all characters in the macro name is the best guideline to follow when creating preprocessor macros to reduce bugs because it helps differentiate the macro from regular code and also avoids potential conflicts with other identifiers. Options A, C, and D are incorrect because using the inline keyword, avoiding arguments, or declaring the macro inside a function do not directly address the issue of reducing bugs. Additionally, using the inline keyword can actually cause issues with debugging and avoiding arguments limits the functionality and flexibility of the macro. Finally, declaring the macro inside a function unnecessarily adds complexity and can potentially cause errors. Therefore, option B is the most suitable guideline to follow in this scenario.
