How do i go from a file containing data, like ...

MJ914
Porsche
914-6
Irish_Green
2
2700
30000
40000

TO

struct car
{
char rego[6];
char make[15];
char model[10];
char colour[15];
int cap[4];
int doors[1];
int costp[6];
int sellp[6];
};

struct car
{
char rego[6];
char make[15];
char model[10];
char colour[15];
int cap[4];
int doors[1];
int costp[6];
int sellp[6];
};


void main()

ifstream fin;

for(x = 0; x++; x > 11 || x = EOF;)
    ifstream fin("cars.dat");
    fin >> car.rego >> car.make >> car.model >> car.colour >> car.cap >> car.doors >> car.costp >> car.sellp >>endl;

I dont think thats the way to do it anyway ...

i think need to use getline();

You're not far off. The first issue I see is that your car struct is using arrays for cap, doors, costp, and sellp. Those fields are just numbers in your file, so they can just be ints. Here is the modified car structure:

struct car
{
  char rego[6];
  char make[15];
  char model[10];
  char colour[15];
  int cap;
  int doors;
  int costp;
  int sellp;
};


You had the right idea for reading in the data -- you can simply use >> on an input stream. You don't need to use endl at the end either. Here's a program that reads all the data in:

int main()
{
  struct car car;
  ifstream fin("cars.dat");
  fin >> car.rego >> car.make >> car.model >> car.colour >> car.cap >> car.doors >> car.costp >> car.sellp;
}
