What ate the errors you are receiving?
The problem I see is where you call the function here:
CODE
cout << "\nTotal" << setw(8) << fixed << setprecision(2) << totalHoursParked << setw(14) << totalParkingFees <<endl <<endl;
First,you are treating the function call like a variable. It is not. As well, you are not actually passing any parameters to the function. It likely needs to resemble the following:
CODE
cout << "\nTotal" << setw(8) << fixed << setprecision(2) << totalHoursParked(hoursParkedCar1,hoursParkedCar2,hoursParkedCar3) << setw(14) << totalParkingFees <<endl <<endl;
Finally, your function prototype declares the function as return type void, whereas you clearly return a double. The prototype will need to be modified.

Ok,
I made the changes suggested and I still get the following 2 errors at compile time:
I appreciate the help.

1 - Error 1 error LNK2019: unresolved external symbol "double __cdecl totalHoursParked(double,double,double)" (?totalHoursParked@@YANNNN@Z) referenced in function _main main.obj
