I am working on a lab and having trouble developing a class to run with the program. I have completed all the arithmetic for the program but not sure how to included the functions in with a "class".

The instructions are to develope class called "rational"- and should contain the following

a. 2 private integer data members representing the numerator and denominator of the rational #

b. a public member function that will allow any function to retrieve the numerator, using an interger return value.

c. a public member function that will allow any function to retrieve the denominator, using an interger return value.

d. a constructor that accepts the numerator and denominator values as arguments.

The main function should included 4 functions (addem, subtracem,mutiplyem,dividem)

I think I have the functions correct. Just not sure on how to include the class and constructor.

#include <iostream>

#include <cassert>

#include <math.h>

using namespace std;

void addem (int n1, int d1, int n2, int d2, int na, int da)

{

da = d1 * d2; // Get common donimator for fractions

na = ((da/d1)*n1)+((da/d2)*n2); // Perform addition on fractions

cout <<n1<<"/"<<d1<<" + "<<n2<<"/"<<d2;

cout <<" = "<<na<<"/"<<da<<"\n";

}

void subtractem (int n1, int d1, int n2, int d2, int na, int da)

{

da = d1 * d2; // Get common donimator for fractions

na = ((da/d1)*n1)-((da/d2)*n2); // Perform subtraction on fractions

cout <<n1<<"/"<<d1<<" - "<<n2<<"/"<<d2;

cout <<" = "<<na<<"/"<<da<<"\n";

}

void multiplyem (int n1, int d1, int n2, int d2, int na, int da)

{

da = d1*d2; // Get common donimator for fractions

na = n1*n2; // Perform multiplication on fractions

cout <<n1<<"/"<<d1<<" * "<<n2<<"/"<<d2;

cout <<" = "<<na<<"/"<<da<<"\n";

}

void dividem (int n1, int d1, int n2, int d2, int na, int da)

{

da = d1*n2; // Get common donimator for fractions

na = n1*d2; // Perform multiplication on fractions

cout <<n1<<"/"<<d1<<" / "<<n2<<"/"<<d2;

cout <<" = "<<na<<"/"<<da<<"\n";

}

int main () {

int numerator1,denominator1,numerator2,denominator2,nummeratoranswer,denominatoranswer; // Declare Numerator and Denominator Variables

cout << "Enter a numerator and denominator of a fraction seperated by a space: "; // Prompt and get numerators and denominators to use in operation

cin >> numerator1 >> denominator1;

cout << "Enter a numerator and denominator of a fraction seperated by a space: ";

cin >> numerator2 >> denominator2;;

addem (numerator1,denominator1,numerator2,denominator2,nummeratoranswer,denominatoranswer);

subtractem(numerator1,denominator1,numerator2,denominator2,nummeratoranswer,denominatoranswer);

multiplyem(numerator1,denominator1,numerator2,denominator2,nummeratoranswer,denominatoranswer);

dividem(numerator1,denominator1,numerator2,denominator2,nummeratoranswer,denominatoranswer);

system ("pause");

return 0;
