help with void getData function

Hello all,
I am working on a program that will read a text file cpart.dat. I want to use a void getData function that I can call in main. I’m having problems to say the least. Here is what I have so far, also: I'm thinking I want to use push_back function in “while (inp)”, to add data to my vectors. Any help would be greatly appreciated

Here is what I have so far:

Code:

---

void getData(ifstream& inp, vector<int>& itemIDs, vector<string>& itemNames,
            vector<int>& pOrdered, vector<int>& pInStore,
            vector<int>& pSold, vector<double>& manufPrice,
            vector<double>& sellingPrice)
{
    int id;
    string name;
    int itemsOrdered;
    double mPrice;
    double sellPrice;
    char ch;

    inp >> id;                                        // Read item id
    inp.get(ch);                                    // Read a newline
    getline(inp, name);                                // Read item name
    inp >> itemsOrdered >> mPrice >> sellPrice;        // Read other info of the item

    while (inp)

    {
                                                    // read the remaining items
    }

}

1.better make the function return int - so you can indicate success/failure to the calling function
2. I'd make the struct that includes all the fields needed and fill the struct - in this case I'd have only 1 vector of structs instead of bunch of vectors.
3. Of course the next step will be to make a struct class to add some functionality to it (like reading/writing all members with jsut one line of code)

I wholeheartedly agree with vart's suggestion: Make it a class, create a read function in the class [and make that one a "all or nothing" - meaning that you either successfully read ALL the data for the struct, or you get "nothing". This means a bit of extra checking to see that you are reading the data correctly, but well worth it the first time you get a "bad" data-file.

Then it's very easy to build a loop to push the data into vector of that class.

Thanks for the replies, I'm not too familar with structs. but I'll look into it.
