Have you ever forked like this???

Hi boys, do you know how many processes the following codes produce? It is 2^5.

So we can get a conclusion which you have n amounts for-statement and you will

get 2^n processes. If you don't know the reason, send me a mail, which i will

describe the reasons in details ;-)

int main(void)
{
 int i = 0;
 pid_t j;

 for (i = 0; i < 5; i++) {
  if (0 > (j = fork())) {
   fprintf(stderr, "Fork Error!\n");
   return 1;
  }
  if (0 == j) {
   fprintf(stdout, "child: %d", getpid());
  } else {
   fprintf(stdout, "parent: %d\n", getpid());
  }
 }
 return 0;
}
