Hero is a code fragment, from our singly-linked list example from class./* DEALLOCATE LIST */for (current_cell = head; current_ce11 != NULL; current_cell = current_cell->next) free(current_cell); Is there a safety issue with this code? Explain. How can you rewrite this code lo make it safe? You can introduce new variables, if needed.

Solution

Hi Please find my answer.

1)

Yes, we are deleteing first : free(current_cell), before forwarding to next node.

2)

current_cell = head;

while(current_cell != NULL){
  
   temp = current_cell; // temp is of type node

   current_cell = current_cell->next;

   free(temp);

}

head = NULL;
