c++ - What does ## in a #define mean? - Stack Overflow
In other words, when the compiler starts building your code, no #define statements or anything like that is left. A good way to understand what the preprocessor does to your code is to get hold of the preprocessed output and look at it.

#define macro for debug printing in C? - Stack Overflow
The double-parentheses are crucial — and are why you have the funny notation in the macro expansion. As before, the compiler always checks the code for syntactic validity (which is good) but the optimizer only invokes the printing function if the DEBUG macro evaluates to non-zero. This does require a support function — dbg_printf() in the example — to handle things like stderr. It ...
Define a method outside of class definition? - Stack Overflow
You can define a function outside of a class and then add it. However, there is a subtle difference in assigning the function to the class or to the instance object.
