Answer 1

#include <stdio.h>
#define A (-B)
#define B (-C)
#define C (5)

int main() {
printf("%d",A);
return 0;
}

I hope that helps

Answer 2

B is not declared, there is no space after define. I canot understand the erro e but undefined b causes a to become undefined.

Answer 3

#include <stdio.h>

#define C 5
#define B -C
#define A -B

int main() {
printf("%i", A);

return 0;
}
