Recursive macro

Question

I'd like to know if it's possible to make recursive macro, I know what macro does, so it shouldn't be used, but I'd like to know if it's possible
For example:
#define fact(x) x * ((x) > 0?fact(x-1):1)
Output(for fact(5)):
5 * 4 * 3 * 2 * 1
Or maybe:
5 * (5 - 1) * (5 - 1 - 1) *...* 1
