TOO many Arguments to Function Call

[jyesudha]

I keep getting this error and i am not sure how to fix it..
:24: too many arguments to function `Car GetCar (ifstream &)'
:48: at this point in file
Below is the code
--------------
#include <iostream>
#include <fstream>
#include <string>

using namespace std;

struct Date
{
int month;
int day;
int year;
};

struct Car
{
float price;
Date purchased;
string customer;
};

Car GetCar(ifstream &dataIn);
// Pre: File dataIn has been opened.
// Post: The fields of car are read from file dataIn.

void WriteCar(ofstream& dataOut, Car car);
// Pre: File dataOut has been opened.
// Post: The fields of car are written on file dataOut,
// appropriately labeled.

int main ()
{
Car car;
ifstream dataIn;
ofstream dataOut;

dataIn.open("cars.dat");
dataOut.open("cars.out");


car = GetCar(dataIn);
while (dataIn)
{
car.price = car.price * 1.10;
WriteCar(dataOut, car);
GetCar(dataIn, car);
}
return 0;
}

//*****************************************************

Car GetCar(ifstream& dataIn)
{
Car car;
dataIn >> car.customer;
dataIn >> car.price >> car.purchased.day
>> car.purchased.month >> car.purchased.year;
dataIn.ignore(2, '\n');
return car;
}

//*****************************************************

void WriteCar(ofstream& dataOut, Car car)
{
dataOut << "Customer: " << car.customer << endl
<< "Price: " << car.price << endl
<< "Purchased:" << car.purchased.day << "/"
<< car.purchased.month << "/"
<< car.purchased.year << endl;
}

GetCar(dataIn, car);

It looks like you meant car = GetCar(dataIn);.

[jyesudha]

so i did make that correct and ran the program but nothing happens. Is that what is supposed to happen? Cause the question is, what is written on file Cars.out.

> Is that what is supposed to happen?
It's your code, ¿what do you want to happen?

> Cause the question is, what is written on file Cars.out.
¿did you have a `cars.out' file?
¿can you open it?
¿can you read it?

¿Did you have a `cars.dat' file?

Try checking the where you put the Cars.out and Cars.dat files. They should be in the same directory as the executable of your program.

There is a lack of symmetry between the functions which write to and read from the file.

The Write function WriteCar() outputs data like this:

Customer: Fred
Price: 2000
Purchased:25/11/2016
Customer: Suzie Soo
Price: 3000
Purchased:28/2/2015

But the read function GetCar() expects data in a format like this:

Fred
2000
25 11 2016
Suzie_Soo
3000
28 2 2015

If you want them to work together nicely, you'll need to decide on a specific data format and use it for both read and write. And modify one or both functions accordingly.

[ne555]

perhaps the program is intended to translate from one format to the other.
Also, the price is updated.

OP: instead of WriteCar(), GetCar() consider overloading the insertion and extraction operators
