Confusion about writting an insert() for a Hash Table...

[joenchinghkg]

I am going to create an method to insert Items inside the hash table,
However, i don't really know what I should code inside the method.

Should I use push or pop because it is based on a list container for my
private attribute.

Here is my code.
hashtable.h
Code:

//HashTable.h
#ifndef HASHTABLE_H
#define HASHTABLE_H

#include <list>

using namespace std;

template <typename KEYTYPE, typename VALUETYPE>
class HashTable
{
public:

void insertItem( const string& key, const VALUETYPE& value
);
VALUETYPE getItem( const string& key ) const;

void dump() const;

private:
enum { TABLESIZE = 20 };

struct KeyValuePair {
KEYTYPE key;
VALUETYPE value;
};
list<KeyValuePair> hashTable[ TABLESIZE ];
unsigned getIndex( const char* key ) const; // Hash Function
};

#include "hashtable.tem"

#endif

hashtable.tem
Code:

//hashtable.tem
template <typename KEYTYPE, typename VALUETYPE>
void HashTable<KEYTYPE,VALUETYPE>::insertItem( const string& key, const
VALUETYPE& value ) {
}

template <typename KEYTYPE, typename VALUETYPE>
void HashTable<KEYTYPE,VALUETYPE>::dump() const {

for( unsigned iCtr = 0; iCtr < TABLESIZE; iCtr++ ) {

cout << "Bucket #" << iCtr << " contains: ";

list<KeyValuePair>::const_iterator iter;
for( iter = hashTable[ iCtr ].begin(); iter != hashTable[ iCtr
].end(); ++iter ) {
cout << '[' << iter->key.c_str() << ',' << iter->value << ']'
<< ' ';
}

cout << endl;
}
}

// End of file

;)

Thanks for advice
