how would I print rational numbers in C++?

I just need to define printRational() and printRationalAsDouble()

everything else seems to work just fine......not sure how to print a fraction though

here is what I got so far.......

#ifndef RATIONAL_H

#define RATIONAL_H

#

using std::ostream;

#

using std::istream;

#

#

class Rational{

public:

rational(int num, int den);

rational(int num);

rational();

int getnum();

int getden();

void input(istream& in);

void output(ostream& out);

bool less(Rational r);

Rational neg();

Rational addition(Rational r);

Rational subtraction(Rational r);

Rational multiplication(Rational r);

Rational division(Rational r);

private:

int numer;

int denom;

};

#include "Rational.h"

#include <iostream>

#include <cmath>

using namespace std;

int Rational::getnum()

{

return numer;

}

int Rational::getden()

{

return denom;

}

Rational::rational(int num, int den)

{

numer = num;

denom = den;

}

Rational::rational(int num)

{

numer = num;

denom = 1;

}

Rational::rational()

{

numer = 1;

denom = 1;

}

Rational::rational addition(Rational r)

{

Rational l;

int a = l.getnum();

int b = l.getden();

int c = r.getnum();

int d = r.getden();

Rational result = ((a * d + b * c) / (b * d));

return result;

}

Rational::rational subtraction(Rational r)

{

Rational l;

int a = l.getnum();

int b = l.getden();

int c = r.getnum();

int d = r.getden();

Rational result = ((a * d - b * c) / (b * d));

return result;

}

Rational::rational multiplication(Rational r)

{

Rational l;

int a = l.getnum();

int b = l.getden();

int c = r.getnum();

int d = r.getden();

Rational result = ((a * b) / (c * d));

return result;

}

Rational::rational division(Rational r, Rational l)

{

int a = l.getnum();

int b = l.getden();

int c = r.getnum();

int d = r.getden();

Rational result = ((a * d) / (c * b));

return result;

}

bool Rational::less(Rational r)

{

Rational l;

int a = l.getnum();

int b = l.getden();

int c = r.getnum();

int d = r.getden();

if ((a * d)<(c * b))

return true;

else

return false;

}

void Rational::input(istream& in)

{

int numer;

int denom;

char slash;

in >> numer >> slash >> denom;

return;

}

void Rational::output(ostream& out)

{

cout<<numer<<"/"<<denom;

}

this is my tester

#include "Rational.h" // include definition of class Rational

#include <iostream>

using namespace std;

int main()

{

Rational c( 2, 6 ), d( 7, 8 ), x; // creates three rational objects

c.printRational(); // prints rational object c

cout << " + ";

d.printRational(); // prints rational object d

x = c.addition( d ); // adds object c and d; sets the value to x

cout << " = ";

x.printRational(); // prints rational object x

cout << '\n';

x.printRational(); // prints rational object x

cout << " = ";

x.printRationalAsDouble(); // prints rational object x as double

cout << "\n\n";

c.printRational(); // prints rational object c

cout << " - ";

d.printRational(); // prints rational object d

x = c.subtraction( d ); // subtracts object c and d

cout << " = ";

x.printRational(); // prints rational object x

cout << '\n';

x.printRational(); // prints rational object x

cout << " = ";

x.printRationalAsDouble(); // prints rational object x as double

cout << "\n\n";

c.printRational(); // prints rational object c

cout << " x ";

d.printRational(); // prints rational object d

x = c.multiplication( d ); // multiplies object c and d

cout << " = ";

x.printRational(); // prints rational object x

cout << '\n';

x.printRational(); // prints rational object x

cout << " = ";

x.printRationalAsDouble(); // prints rational object x as double

cout << "\n\n";

c.printRational(); // prints rational object c

cout << " / ";

d.printRational(); // prints rational object d

x = c.division( d ); // divides object c and d

cout << " = ";

x.printRational(); // prints rational object x

cout << '\n';

x.printRational(); // prints rational object x

cout << " = ";

x.printRationalAsDouble(); // prints rational object x as double

cout << endl;

system("pause");

return 0;

} // end main
