What is the output of the following function and function call?

void calculateCost(int count, float& subTotal, float taxCost);

float tax = 0.0,

subtotal = 0.0;

calculateCost(15, subtotal,tax);

cout << "The cost for 15 items is " << subtotal

      << ", and the tax for " << subtotal << " is " << tax << endl;

//end of fragment

void calculateCost(int count, float& subTotal, float taxCost)

{

      if ( count < 10)

      {

                  subTotal = count * 0.50;

      }

      else

      {

                  subTotal = count * 0.20;

      }

      taxCost = 0.1 * subTotal;

}

#include <iostream>

using namespace std;
void calculateCost(int count, float& subTotal, float taxCost)

{

      if ( count < 10)

      {

                  subTotal = count * 0.50;

      }

      else

      {

                  subTotal = count * 0.20;

      }

      taxCost = 0.1 * subTotal;

}
int main()

{

float tax = 0.0,

subtotal = 0.0;

calculateCost(15, subtotal,tax);

cout << "The cost for 15 items is " << subtotal

      << ", and the tax for " << subtotal << " is " << tax << endl;
      return 0;
}
