Thread: help with fraction division function

i am working on a fraction calculator using functions and i'm stuck. when i compile my code i get an error that says function fracDiv cannot take 0 parameters... can anyone help? here's my code so far:

Code:

#include <iostream>

using namespace std;

//Function prototype: fracDiv
//--------------------------------------------------------------------
// Function:       fracDiv
// Purpose:        Divide two fractions and receive the output as a fraction
//   a/b / c/d = (a*d) / (b*c)
// Preconditions:  parameters: a (int, numerator of first fraction, value parameter)
//   b (int, denominator of first fraction, value parameter)
//   c (int, numerator of second fraction, value parameter)
//   d (int, denominator of second fraction, value parameter)
//   num (int, numerator of result, reference parameter)
//   den (int, denominator of result, reference parameter)
//  
// Postconditions: Returns: int--0 if calculation can be performed,
// 1 if denominator of first fraction is zero
// 2 if denominator of second fraction is zero
// 3 if numerator of second fraction is zero
//   num contains numerator of result 
//   den contains denominator of result
//     
int fracDiv(int a, int b, int c, int d, int& num, int& den);


int main()
{
	int numerator, denominator;
	int a = 0;
	int b = 0;
	int c = 0;
	int d = 0;
	
	cout << "Enter two fractions: " << endl;
	cin >> a >> b >> c >> d;
	
	fracDiv(numerator, denominator);

	
	cout << "Answer = " << numerator << "/" << denominator << endl;
	
	
	
	return 0;
}


//Function
int fracDiv(int a, int b, int c, int d, int& num, int& den)
{


	num = a * d;
	den = b * c;

	
	return 0;
	
}
