Adding Fractions using functions

[jrod]

I have to add two fractions and have the sum be simplified. Here is what I have so far. I can't figure it out at all...we have to use 5 functions including the main. Thanks in advance for any help!

#include <math.h>
#include <iostream>
using namespace std;

void FindGreatestCommonDivider(int, int, int, int, int&, int&);
void CalculateSum(int, int, int&);
int ReadInputtedData(int Num,int Den,int Num2,int Den2);
int EndResult(int Num,int Den,int Num2,int Den2,int SumNum,int SumDen);
void main()
{
int Num,Den,Num2,Den2,SumNum,SumDen;
char Ch;

do
{
cout << "This program adds fractions. 'Y' continues, any other key exits program";
cout << "\n=======================================================================";
cout << "\nEnter Numerator 1==> ";
cin >> Num;
cout << "\nEnter Denominator 1==> ";
cin >> Den;
cout << endl;
cout << "\nEnter Numberator 2==> ";
cin >> Num2;
cout << endl;
cout << "Enter Denominator 2==> ";
cin >> Den2;

}
while (Ch='Y');

EndResult(Num,Den,Num2,Den2,SumNum,SumDen);

cin.ignore(2);
}

B = Temp;
}

{

C = D;
D = Temp2;

Y=A+C;
Z=B+D;

char Ch;



cout << endl << endl;

cout << Den << " " << Den2 << " " << SumDen;
cout << endl << endl;

cout << "Continue? Y or N!==> ";

return true;
