Linked List with C

• Linked lists are the most basic self-referential structures. Linked lists allow you to have a chain of structs with related data.
• So how would you go about declaring a linked list? It would involve a struct and a pointer:
  

  struct llnode {
   data;
  struct llnode *next;
  };
  

  The signifies data of any type. This is typically a pointer to something, usually another struct. The next line is the next pointer to another llnode struct. Another more convenient way using typedef:
  

  typedef struct list_node {
   data;
  struct list_node *next;
  } llnode;
  
  llnode *head = NULL;
  

  Note that even the typedef is specified, the next pointer within the struct must still have the struct tag!
