Addition of Rational Numbers (2)

1. Modify your previous exercise so that it works with the following main program.

   
   struct Rational
   {
       int numerator;
       int denominator;
   };
   
   void add(Rational q1, Rational q2, Rational& q3);
   void print(Rational q);
   
   int main()
   {
       const unsigned short N = 5;
       Rational a[N]   = { {1, 1}, {1, 2}, {1, 3}, {1, 4}, {1, 5} };
       Rational b[N] = { {1, 1}, {2, 1}, {3, 1}, {4, 1}, {5, 1} };
       Rational c[N];
       int i;
       for (i=0; i<N; i++)
       {
           add(a[i], b[i], c[i]);
           print(a[i]);
           cout << " + ";
           print(b[i]);
           cout << " = ";
           print(c[i]);
           cout << endl;
       }
       return 0;
   }
