What mistake can lead to unexpected behavior when defining macros?

Using the inline keyword.
Leaving a space between the macro name and parentheses.
Expanding the macro inside a class definition.
Defining the macro at the beginning of a file.

The correct answer is: Leaving a space between the macro name and parentheses.

One mistake that can lead to unexpected behavior when defining macros is leaving a space between the macro name and parentheses. This is because macros are executed by replacing the macro name with its definition, and if there is a space between the macro name and parentheses, the parentheses will not be recognized and the code will not execute as intended. Therefore, options A, C, and D are all incorrect because they do not directly relate to this potential mistake. Option A refers to using the inline keyword, which is used to indicate that a function should be inlined at the call site, and does not directly relate to defining macros. Option C refers to expanding the macro inside a class definition, which can actually lead to more organized and readable code. Option D refers to defining the macro at the beginning of a file, which is common practice and does not directly relate to the potential mistake mentioned in the question.
