12. Print (safe version)

#advanced

Write a function that prints a listint_t linked list.

  • Prototype: size_t print_listint_safe(const listint_t *head);
  • Returns: the number of nodes in the list
  • This function can print lists with a loop
  • You should go through the list only once
  • If the function fails, exit the program with status 98
  • Output format: see example
