Hi, I did number one but i need #2 and #3

-class name is Pairsummable

-language :C++

Specializations

1) for K = std::string and V = std::string, the initial value for summation should be set to empty string ("").

2) for K = std::string and V = int, the initial value for summation should be set to 0.

3) for K = std::string and V = std::string, the function sum() should concatenate the values stored using , as separator (use operator + to concatenate strings).

Answer for (1)

template

std::string PairSummable<:string std::string>::initial = std::string("");

I just need template specilization, i did number 1 and answered it (see below)

here is the sum function, i tried doing the apecialization, is it correct?

public: static const V& getInitialValue() { return m_initialval; PairSummable() { PairSummable(const K& key, const V& value) : Pair (key, value) { (m_minfield :: key getkey()) { return key getkey) + val; else { return val; void display (std::ostream& os) const os.setf(std::ios::left); os.width(m_minField); os ::getKey() ::getValue() std::strine PairSummable<:string std::string>::n_initialval - std::string(); template std::string PairSummable<:string int>::m_initialval.; template> size_t PairSummable<:string size_t>::sum(const & key, const V& val)const= key +","+ val
