Interesting C question
#include <stdio.h> #define f(a,b) a##b #define g(a) #a #define h(a) g(a) int main() { printf("%s\n",h(f(1,2))); printf("%s\n",g(f(1,2))); return 0; } Just by looking at the program one "might" ... for both the printf statements. But on running the program you get it as: bash$ ./a.out 12 f(1,2) bash$ Why is it so?
