How can I debug macros in C++?

How can I debug macros in C++?

Debugging macros in C++ can be tricky since they are expanded by the preprocessor. You can use the #define directive to create macros and the #line directive to help with line numbers.

What tools can I use to see the expanded macros?

You can use the -E option with the GCC compiler to see the preprocessed output, which shows the expanded macros.

Are there any specific debugging techniques for macros?

Yes, you can use static_assert to check conditions at compile time, and you can also print macro values using std::cout in the code.

Can I use IDE features to help with macro debugging?

Absolutely! Many IDEs like Visual Studio or CLion have features that allow you to step through code and inspect macro expansions.
