Thread: pointer, struct, scanf

I have two structs as follow :

Code:

struct page {
	//the name of the page can not be more than  9 
	char name[10];	
};
struct edge {
 	struct page *page_start ;
 	struct page *page_end ;
};

what I am trying to do is to use scanf to read *(page_start).name from user which it length is max 9 character :

Code:

int
main(void) {
scanf ("%d",&edges_num);
edges = (struct edge *) malloc (sizeof(struct edge)*edges_num);
int i = 0 ;
for (i = 0 ; i < edges_num ; i ++)
	{
	
		scanf("%9s",edges[i].page_start->name);
		
  	}
return 0 ; 
}

It seems scanf is not reading user input , can somebody please help ?
