Question

What I am trying to accomplish here is a dictionary with linked list. There is an array of node pointers. I am trying to initialize each array pointer using malloc. When I remove the for loop, it works fine.

#include <stdbool.h>
#include <stdlib.h>
#include <stdio.h>
#include <ctype.h>

#include "dictionary.h"

unsigned int count = 0;
unsigned int collisions = 0;
unsigned long index = 0;
#define HASHTABLE_SIZE 1999099

// Initialize struct for linked list.

typedef struct node{
     char word[46];
     struct node *next;
  } node;

// Initialize an array of node pointers.

node *hashtable[HASHTABLE_SIZE];


for(unsigned long i = 0; i < HASHTABLE_SIZE; i++)
  //   Error here reads expected "=",";","asm" or __attribute__ before "<"

  {
    hashtable[i] = (node *)malloc(sizeof(node));

  }

Statements are allowed only inside functions.

Add

int main(void) {

before the for loop, and

    return 0;
}

after it. Or, if main is in another file, define some other function to contain the loop.
