Why is this not working?

i wrote this program..sweat all over it...but its not working..can any one help me figure my mistake?

Code:

#include <string>
#include <iostream>
#include <cmath>

using namespace std;

int QuadRoots ( double a, double b, double c, double &r1, double &r2);

int main() 
{
    int result = 0;
    double a, b, c;
    double r1,r2;
	
	cout << "Quadratic coefficients: ";
    cin  >> a  >> b  >> c;
    
	result = QuadRoots(a, b, c, r1, r2);
    if (result == 0)
    {
         cout << "Roots: " << "r1= " << " " << "r2= "
			  << endl;
    }
    else if(result == 1)
    {
         cout << "One of the root is negative";
    }
    else if(result == 2)
    {
         cout << "One of the root is 0";
    }
    return 0;
}

int QuadRoots ( double a, double b, double c, double &r1, double &r2)
{
    int result = 0;
    
    if(a == 0)
    {
         result = 2;
    }
    if((b*b - 4*a*c) < 0)
    {
         result = 1;
    }
    if ((a != 0) && ((b*b - 4*a*c) > 0)) 
    {
         double radical = sqrt(b*b - 4*a*c);
         &r1 = (-b + radical) / (2*a);
         &r2 = (-b - radical) / (2*a);
         result = 0;
    }
    return result;
}

What do you mean it isn't working? Is it producing a compile error?

Code:

&r1 = (-b + radical) / (2*a);
&r2 = (-b - radical) / (2*a);

you already passed the address when calling the function, so no need to set that equal to the address of the variable...take out the &'s and it should work fine.

ok so when i take the & out..the value of r1 n r2 does not appear!

Code:

    if (result == 0)
    {
         cout << "Roots: " << "r1= " << " " << "r2= "
			  << endl;
    }

be nice if you actually outputed the variables

edit: in case you dont know what i mean ....

Code:

    if (result == 0)
    {
         cout << "Roots: " << "r1= " << r1 << " " << "r2= "
			  << r2 << endl;
    }

thanx..it compiles now
