Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++

Question: 1 / 565

What should you do to prevent the unexpected evaluation order of arguments in macros?

Use functions instead of macros.

Use parentheses around all expressions in the macro.

Parentheses should be used around all expressions in the macro to specify the evaluation order. This is because macros perform a direct substitution of its arguments into the code, and without proper parentheses, the order of evaluation can be affected. Option A is incorrect because functions follow a strict evaluation order, which is not required for macros. Option C is incorrect because declaring macros within a function body does not affect the evaluation order of its arguments. Option D is incorrect because expressions are commonly used as macro arguments and avoiding them may not always be feasible.
