Passing an initialization list to a macro

Question

Why doesn\'t the commented out line in the following program compile?

#include 
#include 
using namespace std;

#define F1(a) 1

in         


        

Answer 1

Another workaround is to transform your macro into a variadic macro

#define F1(...) 1

Or, in a more general case:

#define M(a) a

into

#define M(...) __VA_ARGS__
