type def question

the definition is circular I need to define edge in terms of node and node interms of edge?

how do I do it please?

Code:

---

typedef struct
        {
          int nWeight;
          node *Sibling;
        }edge;
       
        typedef struct
        {
          char Name[100];
          edge e[100];
        } node;

---

It won't compile bcoz node is used before definition. So, forward declaration comes to save u. Use this

struct node;
typedef struct
{
int nWeight;
node* Sibling;
}edge;

typedef struct node
{
char Name[100];
edge e[100];
}NODE ;

Now struct node has been declared before use and later defined. It works....

Take a look at the following FAQ...
