[c++ ] classi

[JunkyFunki]

bene...anzi male...oggi ho provato a fare la mia prima classe in c++

vi riporto i codici :

Rational.h

#ifndef RATIONAL_H
#define RATIONAL_H

class Rational {
  		public:
			Rational(int=1,int=1);
		private:
			int num;
			int den;
	       }
#endif

Rational.cpp

#include "Rational.h"

Rational::Rational(int n,int d)
 {
  num=n;
  den=d;
 }

prova.cpp

#include "Rational.h"

void main() {
	      Rational a(2,3), b(3,4), c(1,5), ris;
            }

mi dà i seguenti errori
