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; }; |
