File Stream problems

In 2010 Visual C++ Express, I'm using ...

ifstream inFile("inputfile.dat");
double number;
while(inFile >> number)
{
cout << number << endl;
}

...to read 8 numbers stored in a file into the program, and show them on the monitor. It shows them all correctly and as needed, but I need to store each individual number as already specified doubles. From top to bottom,

  1. Customer 1's Identification #
  2. Balance
  3. Payments outstanding
  4. Purchases that have been made

then the other 4 numbers are the same thing just for a different customer. I've tried a ton of different ways to do it, but each come with:

"Run-Time Check Failure #3 - The variable 'variableName' is 
 being used without being initialized."

and it happens with almost all of the variables. I've searched for anything to help me with this but couldn't seem to find something that would help me to the extent of what I needed.

Assuming that you really want to store these in 8 distinct variables, and not in some aggregate data type:

std::ifstream inFile("inputfile.dat");
double number;

    if(inFile >> cust1id >> cust1bal >> cust1pay >> cust1purch >> 
                 cust2id >> cust2bal >> cust2pay >> cust2purch) {
      std::cout << 
        "Customer 1's Identification #: " << cust1id << "\n" <<
        "Balance: " < cust1bal << "\n" <<
        "Payments outstanding: " << cust1pay << "\n" <<
        "Purchases that have been made: " << cust1purch << 
        "Customer 2's Identification #: " << cust2id << "\n" <<
        "Balance: " < cust2bal << "\n" <<
        "Payments outstanding: " << cust2pay << "\n" <<
        "Purchases that have been made: " << cust2purch << "\n"; 
     }
