Here is a definition of a class called Pairs. Objects of type Pairs can be

used in any situation where ordered pairs are needed. Your task is to write implementations of the overloaded operator >> and the overloaded operator << so that objects of class Pairs are to be input and output in the form

(5,6) (5,-4) (-5,4) or (-5,-6). You need not implement any constructor

or other member, and you need not do any input format checking.

#include <iostream>

using namespace std;

class Pairs

{

public:

Pairs( );

Pairs(int first, int second);

//other members and friends

friend istream& operator>> (istream& ins, Pairs& second);

friend ostream& operator<< (ostream& outs,

const Pairs& second);

private:

int f;

int s;

};
