c++ Simple Class Question

I have a class called htable, when it reaches a certain size it will rehash itself. Heres the pseudo code:

/* Creates new table, and deletes old one. */
Htable Htable::htable_rehash(){
   make new Htable;
   add old values to new table;
        delete old table;
   return new Htable;
}

to call it I would say hashtable = hashtable .htable_rehash();

My question is this: do i need to free the memory in the old hash table in the class, or will it be deleted when i say table = table.rehash?

SHIT CODE YOU FAGGOT

(Map_step(position) % capacity, true) <- WHAT THE FUCK IS THIS YOU IDIOT


int Map::insert(std::string key, std::string value)

{

    // Rehash if we are too full

    if(percent_full() >= REHASH_PERCENT)

        rehash();



    unsigned int position = hash(key)%capacity;



    if(insert_key(key, position))

        return frequencies2[position];



    // There is another key at this position   

    for(unsigned int scanpos=Map_step(position) % capacity; scanpos!=(position); (Map_step(position) % capacity, true))

        if(insert_key(key, position))

            return frequencies2[position];



    return 0;

}



// Returns false if there is another key at that position.

bool Map::insert_key(std::string key, unsigned int position)

{

    if(frequencies[position]==0)

    {

        itemcount++;

        frequencies2[position]=1;

        keys2[position]=key;

        return true;

    }

   

    if(keys2[position]==key)

    {

        frequencies2[position]++;

        return true;

    }

    return false;

}
