Calling and fill a struct from another nested structure (in C)

Hi
The same appears in another site (where people usually like to downvote rather than been helpful to others)

I have an exercise, where the user gives an word as input, and then using structs, the code should make lists and for each entered word count len of characters. So the code looks like the code appended below [1]


I can totally initialize and fill the COUNT [2]

So, ultimately, what needs to be done, is to call struct COUNT from inside struct occurrence and basically for every word that is given, store the length of it in the list. So, how should I initialize the struct occurrence and call the COUNT from within ?

What I have tried:

[1]

typedef struct node
{ int countwords;
struct node *nextnode;
} COUNT;

struct occurrence
{
char word[30];
int count;
COUNT * ocurrence_list_thehead;
};

struct occurrence occurrences[30];

[2]
COUNT *first  = NULL;
COUNT *last  = NULL;

<pre>int counter=0;
int main()
{
  COUNT *node=NULL;
  char textin[N+1];
  while(1) {
  node=malloc(sizeof(COUNT));
  if (node==NULL) 
  {
   printf("Cannot allocate memory");
  return 1;
  }

  fgets(textin, sizeof(textin), stdin);
  if (strcmp(textin , "exit") == 0)
  break;
     else
  {
   node->countwords = strlen(textin);   
   node->next=NULL;
   if (first!=NULL){
      last->next=node;
      last=node;
    }
    else {
     first=node;
     last=node;
    }

struct occurrence *occ = &(occurrences[counter]);

occ->ocurrence_list_thehead-> countwords = strlen(textin);
counter++;
  }

 
 node=first;
 while (node!=NULL){
     printf ("\n %d length of string", node->countwords);
     node=node->next;
 }
    
    return 0; 
  }
     
}
