Getting errors?

[Dkob1]

I'm getting two errors:
1) IntelliSense: no instance of constructor "Rational::Rational" matches the argument list argument types are: (int)
2)'Rational::Rational(const Rational &)' : cannot convert parameter 1 from 'int' to 'const Rational &'

Code:

//Program to reduce rational numbers
#include<iostream>
using namespace std;
//Rational class defintion
class Rational
{
private: 
   int num, denom; //member var.
public: 
   Rational(int aval, int bval); //constructor
   double reduce(); //function to reduce rational number
   friend ostream & operator<<(ostream & out, Rational&r); //overloaded stream output operator
};
stem("pause"); 
return 0;
}

Try Rational r(14,-32); //Declare objects of Rational class with values on line 49.

ok that helped, but the other error, I'm not sure how to fix:
Error 1 error C2664: 'Rational::Rational(const Rational &)' : cannot convert parameter 1 from 'int' to 'const Rational &'

I think I got it actually, thanks.
