File I/O Issue

[Dreadfrost]

Ok general prog overview.
-read records from text file called hours.txt
-stores records in vector of datatype emp
-emp is custom class with with constructor of
Emp():fName(""), lName(""), hours(0.00), rate(0.00){;}
so (string, string, double, double)
formatted to (string, double) (concatenate names, and multiple numbers)

so what im doing is:
reading the file using

ifstream readData;
readData.open("hours.txt");

and put the fields values into the object Emp. Multiple Emps are stored into a vector. I close the stream readData via
readData.close();

Now i open an output stream with

ofstream writeData;
writeData.open("pay.txt");

I concatenate the names multiple the numbers and output to a pay.txt file. close file with. FYI ALL THIS WORKS FILE
writeData.close();


Now i reopen the hours.txt to append data. With
writeData.open("hours.txt", ios::app);
(hours.txt instead of pay.txt) write data to it....close it
writeData.close();

now i repeat the first part opening hours.txt for input and the appended info dosnt come up. However when I exit and repeat or go look directly at the file its there. Its like its read hours.txt from a buffer it had, not the newly appended one. code below simplfied. FYI exit to initial while loop not coded :)

int main()
{
    vector<Emp> vec;                    //vector to hold employee information
    Emp temp;                           //temp emp object to gp into vector
    ifstream readData;                  //stream for reading files
    ofstream writeData;                 //stream for writing to files
    int i = 0;                          //counter for loop and vector elements
    double tempDbl;                     //temp double for reading data
    double totalPay = 0.00;             //total dollar paid out to employees
    bool done = 0;                      //value to indicate program run complete
    string response;                    //variable for users responses
    string tempStr;                     //temp string for reading data
    
    //users continues using program
    while (!done)
    {
        //users choice to add employee or display and write report  
        cout << endl << "Display report or add employee? (RPT/EMP): ";
        cin >> response;
        
        //----------DISPLAY AND WRITE REPORT----------//
        if (response == "RPT")
        {
           //open file to read data from
           readData.open("hours.txt");
           
           //if opening file failed
           if (readData.fail()) 
           {
              ...
           }
           else
           {
               //read data from file store into vector
               while (!readData.eof())
               {
                     readData >> tempStr;
                     temp.SetFirst(tempStr);
                     readData >> tempStr;
                     temp.SetLast(tempStr);
                     readData >> tempDbl;
                     temp.SetHours(tempDbl);
                     readData >> tempDbl;
                     temp.SetRate(tempDbl);
                     vec.push_back(temp);
                     i++;
               }
           }
           //close file
           readData.close();
           
           //open file to write to
           writeData.open("pay.txt");
           i = 0;
           
           //write formated data to file and console
           while (i < vec.size())
           {
               writeData << vec[i].GetName() << " $" << vec[i].GetPay() << endl;
               totalPay += vec[i].GetPay();
               cout << vec[i].GetName() << " $" << vec[i].GetPay() << endl;
               i++;  
           }
           
           //close file
           writeData.close();
        }
        else if (response == "EMP")
        {
             cout << endl << "Enter employee data in the format of: "
             << endl << "FIRST LAST HOURS RATE" << endl;
              
             writeData.open("hours.txt", ios::app);
             cin.ignore();
             getline(cin, tempStr);
             writeData << endl << tempStr;
             writeData.close();
        }
    }
    cout << endl << endl;
    system("pause");
    return 0;   

If the class Emp is required ill post it.

Got an update on it. When first execution of RPT goes fine, but the stream is unsynced at the end on storing the data. Then fomr then on afterwards it give a error when i try and display the sync status after ive appended to the file. I've double checked and it definitly closes the file each time so idk.
