Pair Module

Design and code a class template named Pair for managing a key-value pair. The template parameters identify the types of the key and value objects that constitute a Pair object:

K: the type of the key

V: the type of the value

This module should not use or know the type Set!!

Public Members

default constructor

Pair(const K& key, const V& value): copies the values received in the parameters into instance variables

const K& key() const: returns the key component of the pair

const V& value() const: returns the value component of the pair

void display(std::ostream& os) const: inserts into the parameter the key and value of the pair in the following format

KEY : VALUE

Free Helpers

std::ostream& operator& pair): calls the function Pair::display() to insert a pair into the stream.

needs to be asa module , cpp and h file
