Help! What's wrong with my code? How do I read data from a file?

This file is like.

John Doe 789-89-7897 7.25 45 F
Jane Smith 456-56-4564 8.20 30 P
Luke Warm 123-23-1231 5.26 48 F

I need to read from this file and then output a report with columns and rows.

This is my code so far, but somethings wrong, it keeps crashing.

Code:

---


# include <iostream>
# include <fstream>
# include <iomanip>
# include <string>

using namespace std;

int main ()
{

        const int LENGTH=10;

        int num_records=0;
        char FName[LENGTH];
        char LName[LENGTH];
        char ssNum[LENGTH];
        float hrWage[LENGTH];
        float weekHrs[LENGTH];
        char empStatus[LENGTH];

        float timePay=0;
        float overHrs=0;
        float overPay=0;
        float overTime=0;
        string statDisplay;
       
        float netPay=0;
        int unionFee=5;

cout<<"First Name    Last Name    SSN          Wage    #Hrs  Reg.Pay  OT Pay  Status    NetPay    "<<endl;


        //open file
        ifstream data_file ("F:\\2011 Spring\\C++\\Data Files\\Ch11 Exercise 1\\DataFile.txt");

        //check for an open file
        if (data_file.is_open())
        {
                data_file>>FName[num_records]
                                >>LName [num_records]
                                >>ssNum [num_records]
                                >>hrWage [num_records]
                                >>weekHrs [num_records]
                                >>empStatus [num_records];

                while(!data_file.eof())
                {
                        num_records++;

                        data_file>>FName[num_records]
                                >>LName [num_records]
                                >>ssNum [num_records]
                                >>hrWage [num_records]
                                >>weekHrs [num_records]
                                >>empStatus [num_records];

                                timePay=hrWage[num_records]*weekHrs[num_records];

                                if (weekHrs[num_records]>40)
                                {
                                        overHrs=weekHrs[num_records]-40;
                                        overPay=hrWage[num_records]*1.5;
                                        overTime=overHrs*overPay;
                                }
                                else
                                {
                                        overTime=0;
                                }

                                if(empStatus[num_records]=='F')
                                {
                                        statDisplay = "Fulltime" ;
                                }
                                else
                                {
                                        statDisplay = "Parttime";
                                }

                                netPay=(timePay+overTime)-unionFee;

                               
                                cout<<left<<setw(15)<<FName;
                                cout<<left<<setw(14)<<LName;
                                cout<<left<<setw(16)<<ssNum;
                                cout<<left<<setw(9)<<hrWage;
                                cout<<left<<setw(6)<<weekHrs;
                                cout<<left<<setw(9)<<timePay;
                                cout<<left<<setw(8)<<overTime;
                                cout<<left<<setw(11)<<statDisplay;
                                cout<<left<<setw(11)<<netPay<<endl;

                }
                data_file.close();
        }
        else
        {
                cout<<"Error: File is unable to open."<<endl;
        }
        return(0);
}

Use your debugger to help you determine the point of the crash. This gives you a reference as to where to start looking. (The actual mistake could have happened well before the crash, but at least you can rule out what comes after the crash for now.)

One problem I see is that FName, LName and ssNum should be arrays of std::string objects, not char. Also, do not use eof() to control a loop like that. Rather, write:

Code:

---

while (data_file >> FName[num_records]
                >> LName[num_records]
                >> ssNum[num_records]
                >> hrWage[num_records]
                >> weekHrs[num_records]
                >> empStatus[num_records])

Thank you so much. That helped alot. there was a few other problems with it too, but I was able to figure it out once I did your suggestion.
