Bool print variable in c

Print bool c

// there is no way of pretty-print a boolean with printf
printf("%i", true);  // will print 1
printf("%i", false); // will print 0

// but we can create a macro
#define formatBool(b) ((b) ? "true" : "false")
printf("%s", formatBool(true));  // will print true
printf("%s", formatBool(false)); // will print false

int main(){
  int o = true;
  printf("%i", o);
  /*

  */
  int q = false;
  printf("%i", q);
  /*
