pset5 load function help. what am i doing wrong?

Question

bool load(const char* dictionary)
{
int counter = 0;
int hash = 0;

// define node data type for linked list
typedef struct node
{
    char word[LENGTH + 1];
    struct node* next;
}
node;


// declare the hash table
node* hash_table[27];


// loop through each dictionary word
while (!=EOF)
{

    // create new node
    node* new_node = malloc(sizeof(node));

    new_node -> next = NULL;

    // check for NULL
    if (new_node == NULL)
    {
        exit(1);
    }


    // read in dictionary word
    fscanf(dictionary, "%s", new_node -> word);

    //increment dictionary word count
    counter++;

    // hash dictionary word
    int hash = toupper(new_node -> word[0]) - 'A';

    // insert word into hash table


    hash_table[hash] = new_node -> next;
    new_node -> next = hash_table[hash] -> next;
    hash_table[hash] -> next = new_node -> next;

}




return false;
}

these are my errors

Lots of syntax errors.

while (!=EOF)

The "not equal to" operator, !=, operates on two values or variables, comparing them. This statement has one value, EOF. The correct operator would be the not operator, !.

fscanf(dictionary, "%s", new_node -> word);

dictionary is a constant character string, the file name, not a file pointer. I'll leave it to you to read the documentation on fscanf to figure out how to fix this.

Later errors may be side effects of the fscanf problem.
