Here line 12 and 14 should output the same value (expected output 1)

But why when I call range(i,mn,mx) it outputs 0?

you should write 

#define range(i,mn,mx) (((i) >= mn) && ((i) <= mx)?1:0)

instead of

#define range(i,mn,mx) ((i >= mn) && (i <= mx)?1:0)

      If you write #define range(i,mn,mx) ((i >= mn) && (i <= mx)?1:0) then range(x||y,0,1) will be like ((x||y >= mn) && (x||y <= mx)?1:0) => ((x||(y >= mn)) && (x||(y <= mx))?1:0)
