int main( int argc, char** argv) {
  if ( argc > 2 || argc == 1 ) {
    printf("Fibonacci takes one postitive integer greater than two as it's argument\n");
    return EXIT_SUCCESS;
  }
  int a, b;
  a = 0;
  b = 1;
  printf( "%d", b );
  for( int i = 0; i + a <= atof( argv[1] ); b = i ) {
    i = a + b;
    a = b;
    printf( ", %d", i );
  }
  printf("\n");
  return EXIT_SUCCESS;
}
