What output would be produced by the following program segment?

................

void fn(int &, double &); // function prototype (pass-by-reference)

void fn(int, int); // function prototype (pass-by-value)

int main()

{

int integer1 = 4, integer2 = 3;

   double sum = 1.5;

   fn(integer1, integer2);

   cout << "integer1=" << integer1 << ", integer2="

        << integer2 << ", sum=" << sum << endl;

       fn(integer1, sum);

   cout << "integer1=" << integer1 << ", integer2="

        << integer2 << ", sum=" << sum << endl;

   return 0;

}

void fn(int &x, double &y)

{

     x -= 2;

     y = x*y;

     cout << "y=" << y << endl;

     }

void fn(int x, int y)

{

     x -= 3;

     y = x*y;

     cout << "y=" << y << endl;

     }
