problem with Structs/NULL

For an assignment, we have to use hashing to insert a dictionary(an array of linked lists) but I seem to be unable to set any of them to NULL.

btw: note this is my first C program, I learned to program entirely in Java prior to this.

Code:

---


#include<stdio.h>
#include<stdlib.h>
#include<string.h>

#define WORDSIZE 32
#define TABLESIZE 2000
#define HASH_VALUE 13

int tablePosition;
struct LIST table[TABLESIZE];                //table

//global methods
int hash(char string[]);


struct NODE
{
        char word[WORDSIZE];
        struct NODE *next;
};

struct LIST
{
        struct NODE listTop;
};

struct QUEUE
{
        struct NODE queueTop;
        struct NODE queueBottom;
}queue;

int main(int argc, char *argv[])
{

        int i;
        int arg;
        char string[WORDSIZE];
        FILE* word;

        {
                void insert();
        }

        arg=getopt(argc,argv,"d:");

        if(-1!=arg)
                word = fopen(optarg,"r");
        else
        printf("OOPS");


        //sets the first character in each list to NULL to check for empty lists
        for(i=0;i<TABLESIZE;i++)
                table[i].listTop.word=NULL;

        while(fgets(string,WORDSIZE,word))
        {
printf("%s",string);
//                insert(string);
        }




        fclose(word);
        return EXIT_SUCCESS;
}

>>table[i].listTop.word=NULL
make it
>>table[i].listTop.word[0] = '\0'
