Rational Numbers

1. Define a class CRational with two data members (numerator and denominator), and two member functions.
2. Addition: a/b + c/d = (ad+bc)/bd
3. Reduction (約分) : ac/bc = a/b
4. Store your definition of class CRational in "rational.h".
5. Test your class with the following main program:

   
   #include "rational.h"
   
   int main()
   {
      CRational a(1, 4);
      CRational b(3, 4);
      CRational c = a.Addition(b);
      c.Print();
      c.Reduction(); c.Print();
      CRational d = c; d.Print();
      CRational e(c); e.Print();
      return 0;
   }
   
   

6. If compiled with the -D_DEBUG option, the output may look like

   Constructor(1,4) called
   Constructor(3,4) called
   Copy Constructor(3,4) called
   Constructor(0,1) called
   16/16
