Seg fault in creating Hash Table

[noob_sof]

Can somebody please explain to me, why i am getting a seg fault when i call createhashtable from main function?

#include<stdio.h>
#include<stdlib.h>
typedef struct node* Node;
struct node
{
    char* word;
    Node next;
};
typedef struct htnode* ht;
struct htnode
{
    int count;
    ht head;
};
struct hashtable
{
    int count;
    int size;
    ht* table;
};
struct hashtable* createhashtable(int size)
{
    struct hashtable* h;
    int i;
    h = (struct hashtable*)malloc(sizeof(struct hashtable));
    h->size = size;
    h->count = 0;
    h->table = (ht*)malloc((sizeof(struct htnode))*(h->size));
    for(i=0;i<size;i++)
    {
        h->table[i]->count = 0;
        h->table[i]->head = NULL;
    }
    return h;
}

Your main is not included in the code. What is the constraint on size?

No constraint on size, this code I was writing just for practice.
In the main(), I will just initialize a hash table by passing any value of size, say 20.

Anyone?
