Yeah right... we are forced to programm some good old C at our university... ;) So here's my problem:

We got the assignment to program a little program that show a fibonacci sequence from 1 to n 1 to 18 works great. But from 19 the program does nothing at all and just exit as it's done. I can not find the error... so please give me a hint. :)

#include
#include
#include
#include

int main(int argc, char **argv)
{
  pid_t pid;
  int fib[argc];
  int i, size;
  size = strtol(argv[1], NULL, 0L);
  fib[0] = 0;
  fib[1] = 1;
  pid = fork();
  printf("size = %d \n", size);
  if(pid == 0){
    for(i = 2; i  0){ // Parent, because pid > 0
    wait(NULL);
    printf("\n");
    exit(1);
  }
}

Thanks already!
