Thick n00b needs help with File i/o and structs

OK folks im being as dense as a very dense thing here. Ive searched for tutorials etc and i cant seem to figure it out in the way i want to use it.

I want a struct to hold data on a supplier, namely and ID for the supplier and a supplier name.

im currently using :

Code:

---

struct Suppliertype
{
        char *cName;
        int iSuppId;
};

---

I then want the user to enter the new data and append this data to a text file (supplier.txt).

im currently trying it like this:

Code:

---

void NewSupplier(void)
{
        char sNewSupplier[50];

        cout << "Enter the name of the new supplier: ";
        cin >> sNewSupplier;

        ofstream SuppFile("supplier.txt", ios::app);
        SuppFile << sNewSupplier << "," << "/n";
}

---

i know i aint using the struct in this coz this is the problem - i dunno how to.

After ive appended the file i want to have a separate function to read the text file and display the list of suppliers on the screen.

This is for part of my Uni degree (only 1st year tho) so i aint gonna be nicking peeps code for commercial use - i just want to know how to do this.

Thanks in advance :)

Declare an object of the structure in the second function. Load the data into the structure using cin and the dot operator. You are opening the file correctly, but you need to cast the object to a char* then write the sizeof the structure to the file. If you still need some help try doing a search. You should have no problem finding some examples in previous threads because this topic has been discussed many times. Have a great day.

Ok as per structures you implement your strucure like so:

Code:

---

Suppliertype Supplier1; //creates a variable of your struture type
Supplier1.iSuppId = (whatever); //you use variables like this

fstream SuppFile("supplier.txt", ios::app | ios :: out);
SuppFile << sNewSupplier << "," << "/n";
SuppFile << "Supplier Id: "<<Supplier1.iSuppId
SuppFile.close();

---

Hope this helps :)

Cheers folks - much appreciated :)
