Such a simple problem

Title says its all!

Cannot figure out why when I print "totalFee" im getting 0.00 as output although I am passing it by reference to the function. At no point can I see why the variable is not adding the "charge" value. I am not getting errors or warnings. It looks like quite a small mistake im making.

Can anyone see what I am doing wrong?

Code:

---

#include <iostream>
#include <iomanip>

// function prototype
double calculateCharge ( double, double& );

// main function - driver //////////////////////////////////////////////////////
//
int main ( void )
{
        std::cout << std::setprecision ( 2 ) << std::fixed;

        double time1 = 0,
                  time2 = 0,
                  time3 = 0,
                  totalTime = 0,
                  totalFee = 0;

        std::cout << "Enter stay times for three cars: ";
        std::cin >> time1 >> time2 >> time3;

        totalTime = time1 + time2 + time3;

        std::cout << "\nCAR\tSTAY\tFEE\n\n"
                          << " 1\t" << time1 << "\t" << calculateCharge ( time1, totalFee )
                          << "\n 2\t" << time2 << "\t" << calculateCharge ( time2, totalFee )
                          << "\n 3\t" << time3 << "\t" << calculateCharge ( time3, totalFee )
                          << "\n\nTotal Time: " << totalTime
                          << "\nTotal Fee: " << totalFee << std::endl;

    std::cin.get(); // freeze console output window
        std::cin.ignore();

    return 0; // return value from int main
}

// function to calculate the charge
// for each car stayed
double calculateCharge ( double x, double &rFee )
{
        double charge = 0;

        if ( x <= 3.00 )
        {
                charge = 2.00;
                rFee += charge;
        }

        if ( x > 3.00 )
        {
                double timeOverStandard = 0,
                          additionalCharge = 0;

                timeOverStandard = x - 3.00;
                additionalCharge = timeOverStandard * 0.5;

                charge = 2.00 + additionalCharge;
                rFee += charge;
        }

        if ( x == 24.00 )
        {
                charge = 10.00;
                rFee += charge;
        }

        return charge;
}

Elementary my dear Watson. One possible fix... change:

Code:

---

        std::cout << "\nCAR\tSTAY\tFEE\n\n"
                          << " 1\t" << time1 << "\t" << calculateCharge ( time1, totalFee )
                          << "\n 2\t" << time2 << "\t" << calculateCharge ( time2, totalFee )
                          << "\n 3\t" << time3 << "\t" << calculateCharge ( time3, totalFee )
                          << "\n\nTotal Time: " << totalTime
                          << "\nTotal Fee: " << totalFee << std::endl;

---

To:

Code:

---

std::cout << "\nCAR\tSTAY\tFEE\n\n"
        << " 1\t" << time1 << "\t" << calculateCharge ( time1, totalFee )
        << "\n 2\t" << time2 << "\t" << calculateCharge ( time2, totalFee )
        << "\n 3\t" << time3 << "\t" << calculateCharge ( time3, totalFee )
        << "\n\nTotal Time: " << totalTime;
std::cout << "\nTotal Fee: " << totalFee << std::endl;

I'll let you think about the "why".

Good one.
