Linked List of struct
 

I am creating a linked list which links a struct of data together. However, this is my problem, if I declare struct Node first then the Event type wont exist, but if I declare struct Event first then nodePtr wont exist....im kinda stuck here as to how I should declare them.

struct Event

{

       void addEvent();

       

       tm startTime, endTime;

       string eventItem;

       string eventNotes;

       char allDay;

       nodePtr head, tail;

                     

};





struct Node

{

       Event eventNode;

       Node *next;

};



typedef Node* nodePtr;

Not sure of what you want to accomplish here. This piece of info might help getting the same results using a different method.

ok what im trying to do have a list of Events (which are actually a struct type containning data such as time date etc). And my problem as can be seen above is that I do not know how to resolve their declarations. I cant declare struct Event first because it contains pointers to the next Event struct. And I cant declare struct Node first because the node is of Event type.

struct Event

{

       void addEvent();

       

       tm startTime, endTime;

       string eventItem;

       string eventNotes;

       char allDay;

       nodePtr *head, *tail; //-- a pointer!, maybe...

                     

};





struct Node

{

       Event *eventNode; //-- a pointer!, maybe.

       Node *next;

};



typedef Node* nodePtr;

Maybe, you confused the functionality of Event struct and Node struct.

There are two ways to reach you objective.
First,

struct EventNode

{

  tm startTime, endTime;

  string eventItem;

  string eventNotes;

  char allDay;

  

  EventNode* next;

};



struct EventList

{

  void addEvent();

  ... // other member functions used to sustain the list 

private:

  EventNode* head;

  EventNode* tail;

};

another way use the list of STL to store the event.

struct Event

{

  tm startTime, endTime;

  string eventItem;

  string eventNotes;

  char allDay;

};



std::list<Event> eventList;

ah ok i get what u mean
