Hi. I have the following class (modified from Data Structures for Game Programmers by Ron Penton) that implements a hash table.
template <class DataType>
struct hash_entry
{
  std::string m_Key;
  DataType m_Data;
};

template <class DataType>
class hash_table
{
  protected:
    int m_Size;
    int m_Count;
    std::vector< std::list< hash_entry<DataType> > > m_Table;
    
    unsigned long int hash(std::string Key);
    
  public:
    hash_table(int p_Size) : m_Size(p_Size), m_Count(0), m_Table(p_Size) { }
    ~hash_table() { m_Size = 0; m_Count = 0; }
    
    void insert(std::string p_Key, DataType p_Data);
    hash_entry<DataType>* find(std::string p_Key);
    void remove(std::string p_Key);
};

Here is the find() function...
template <class DataType>
hash_entry<DataType>* hash_table<DataType>::find(std::string p_Key)
{
  int Index = hash(p_Key) % m_Size;
  std::list< hash_entry<DataType> >::iterator EntryItr = m_Table[Index].begin();
  while(EntryItr != EntryItr.end())
  {
    if((*EntryItr).m_Key == p_Key) { return(&(*EntryItr)); }
    EntryItr++;
  }
  return(NULL);
}

Whenever I compile, I receive the warnings
[Warning] ` std::list<hash_entry<DataType>, std::allocator<hash_entry<DataType> > 
[Warning] implicit typename is  deprecated, please see the documentation for details
Both warnings point to this line in the find() function...
std::list< hash_entry<DataType> >::iterator EntryItr = m_Table[hash(p_Key) % m_Size].begin();
Any idea how to fix this? If you find any other errors / problems, please share those too. Thanks in advance.
