Question

I have this structure :

typedef struct xmlelem{
Char         *Element_name;
Char         *Element_Text;  
pAttr_Element    attr_arr[M];
Xml_Element     *parent;
Xml_Element     *children[N];
Int         depth;
Int         num_of_children;
Int         num_of_attr;
}Xml_Element,*pXml_Element

I was wondering about the children and the attr_arr .
For the attr_arr – is it a pointer to an array where every cell is from type pAttr_Element or from type attr_Element ? How can I figure out if the cell is a pointer or the structure itself? How can I define both of them? I’m kind of lost..

sorry – here is the pAttr_Element:

 typedef struct {
   char *name;
   char *value;
 }Attr_Element,*pAttr_Element

another editing ,trying to be clearer

I understood thanks to the guys here that this is an array,where each cell is a pointer of type pAttr_Element.

I also understand now that declaring : Attr_Element[10] is an array where each cell is type of my structure

the only thing missing is how I define a pointer to an array where each cell is from type Attr_Element ? and not a pointer

Thanks!

Answer 1

Here I have assumed attr_Element is structure and pAttr_Element is typedef for type of pointer to this structure.

typdef atr_Element* pAttr_Element;

In this case, pAttr_Element attr_arr[M]; each element of attr_arr is a pointer variable to attr_Element. That means attr_arr is a array of pointer of type attr_Element

If you want to define array of elements of type attr_Element, directly use that type as below

#define SIZE_OF_ELEM 20

struct attr_Element attr_arr[SIZE_OF_ELEM];
