(Solved) : Header File Need Implementation Several Functions Retrieve Merge Issubset Thank Class Ord Q31217909 . . . .

I have this header file and I need the implementation forseveral functions: retrieve, merge and isSubset. Thank you.

class OrderedList : public List<DataType>

{

public:

static const int DEFAULT_MAX_LIST_SIZE = 10;

// Constructor

OrderedList ( int maxNumber = DEFAULT_MAX_LIST_SIZE );

// Modified (or new) list manipulation operations

virtual void insert ( const DataType &newDataItem ) throw (logic_error );

virtual void replace ( const DataType &newDataItem ) throw (logic_error );

bool retrieve ( const KeyType& searchKey, DataType&searchDataItem );

// Output the list structure — used in testing/debugging

void showStructure () const;

// In-lab operations

void merge ( const OrderedList<DataType,KeyType>&other ) throw ( logic_error );

bool isSubset ( const OrderedList<DataType,KeyType>&other );

// Inheritance using templates is somewhat ugly
