Pass be refrence

[Yankee99402]

I am confused with passing my values from my function to my other function by refrence ( not using a pointer ) I am trying to have my houremployee function to be able to change the values of hours and wage. The project requires this done with a refrence and every time I try I get different errors. Can someone explain what the best way to do this would be?

void employeePayRoll::printHourEmployee()
{
   double hours, wage;
   cout << "Please enter the hours worked by the employee" << endl;
   cin >> hours;
   cout << "Please enter the hourly wage of the employee" << endl;
   cin >> wage;
   hourEmployee(hours,wage);

double employeePayRoll::hourEmployee(double hourWorked,double hourWage)
}

You pass by reference by adding &. That'll mean your function will have access to your original variable rather than make a copy like passing by value does.

It would also be nice if you posted your errors since we cant read minds :)

double employeePayRoll::hourEmployee(double hourWorked,double hourWage)

I dont know what youre doing here. That's not how you call a function?

Example of pass by reference -

void changeVariable(int& x);

int main()
{
    int x = 5;
    changeVariable(x);
    std::cout << "X: " << x << std::endl;
}

void changeVariable(int& x)
{
    x = 10;
}

X: 10
