    freeing hash table

    i want to free the hash table. does this function look correct?

    Code:
    void free_table (void)
    {
    	int i;
    	struct hash_list *v, *temp;
    	
    	for (i = 0; i < HASHSIZE; i++){
    		v = hashtab[i];
    		while (v != NULL){
    			temp = v;
    			v = v -> next;
    			free (temp -> name);
    			free (temp);
    		}
    	}printf ("Done\n");
    }

    Which hash table? Yours? It's hard to tell you if your code is correct without knowing how you've structured and built the hash table.

    >does this function look correct?
    It looks okay at a glance. Why do you ask?
    My best code is written with the delete key.

    The code formatting could be better, especially the final printf following a brace, should be on a new line.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Code:
    struct hash_list{ char *name; struct hash_list *next; } hash_list;
    
    #define HASHSIZE 6151
    
    static struct hash_list *hashtab[HASHSIZE];
    
    void init_table(void)
    {
    	unsigned int i;
    	for (i = 0; i < HASHSIZE; i++)
    		hashtab[i] = NULL;
    }
    here is how i built my hash table

    It looks correct.
    Did you have some errors or were just wondering ?
