Inserting in linked list

[johngoodman]

I'm trying to make a function that lets me pass an index and a string and will insert the string at that index in the linkedlist... any help would be appreciated

typedef struct node {
  char* value;
  struct node* next;
} LinkedList;
  
  
void llAddAtIndex(LinkedList** ll, char* value, int index) {
  
  LinkedList* newNode =(LinkedList*)malloc(sizeof(LinkedList));
  newNode->value = value;
  LinkedList* prevNode = NULL;
  LinkedList p;
  p = ?????
    
  for(int i = 0; i < index; i++){
      prevNode = p;
    p = p->next;
  }
    if (prevNode) { 
      prevNode->next = newNode;
      newNode->next = p;
    } else { 
        head = newNode;
        newNode->next = p;
      }
}

Double-posting your question doesn't make answers come any quicker.

Quite the opposite.

Do you have a question?

You have a variable called prevNode. So what is p for?
Where should prevNode point to start iterating through the list?

How To Ask Questions The Smart Way
Try to imagine a board where everyone behaved like you do, posted every question twice - and then someone upped the ante by posting 3 times.
How quickly do you think the board would become a spam-fest and all the people who help would bugger off and find something better to do with their time.

Oh, and this is what happens to duplicate threads - CLOSED!
