Assignment Help:
self test exercise 17 asked you to overload the operator >> and the operator << for a class Pairs. Complete and test this exercise. Implement the default constructor and the constructors with one and two int parameters. The one parameter constructor should initialize the first member of the pair; teh second member of the pair is to be 0.
Overload biinary operator + to add pairs according to the rule
(a, b) + (c, d) = (a + c, b, + d)
overload operator - analogously
overload operator * on Pairs and int according to the rule
(a, b) * c + (a * c, b * c)
write a program to test all the member functions and overloaded operators in your class definition

istream& operator >> (istream& ins, Pairs& second)
{
char ch;
ins >> ch; // discard initial ''(''
ins >> second. f;
ins >> ch; // discard comma '', ''
ins >> second. s;
ins >> ch; // discard final '') ''
return ins;
}
ostream& operator << (ostream& outs, const Pairs& second)
{

outs << ''( '';
outs << second. f;
outs << '', ''; // you might prefer ", "
// to get an extra space
outs << second. s;
outs << '')'' ;
return outs ;
}
