A Vector of Rational Numbers

1. Use the CRational class you defined in the previous exercise. Create a vector of CRational.
2. Combine your class with the following main program:

   
   int main()
   {
       string s;
       vector<CRational> mydata;
   
       while (cin >> s)
       {
           CRational c(s);
           mydata.push_back(c);
       }
   
       std::sort(mydata.begin(), mydata.end(), less);
       for (int i=0; i<mydata.size(); i++)
       {
           mydata.at(i).Print();
       }
       return 0;
   }
   
   

3. You need to define a function bool less(CRational, CRational) to help sort() comparing rational numbers.
