    Im really am stuck with this half of the program. Seen that im no good at I/O Streams i am hoping some one could help me with this..

    what i am looking to do is Ask A User to enter a Seat No. Search the Text File. once you find that No.

    Then allow the User to Update the Name,

    Over Write the old Name in the Text file with the New Name the User Enters. but its not working

    {
            int recNumb;
            
            fstream myFile("AirLine.text", ios::in | ios::out | ios::app | ios::binary);
            myFile.seekg(0, ios::beg);
            
            cout << "Enter Passenger Seat Number:";
            cin >> recNumb;
             
            passenger p;
            while (!myFile.eof())
            {
                myFile.read((char*)&p, sizeof (p));
                
                
            
                if(recNumb == stArray[i].seat_number)
               {   
             
                    cout << " Enter Passengers New Name:";
                    cin.getline(stArray[i].Newname,30);
             
                  
             
               }
             
                
                
                long pos = Myfile.tellg();
                pos -=sizeof(passenger);
                myFile.seekp(pos,ios::beg);
                
                 stArray[i].name = stArray[i].Newname;
                
                myFile.write((char*)&p, sizeof(p));
                
            }
         
            
                   else 
                   
                   cout<<"Passenger  not found"<<endl;
                   
                 
                   myFile.close();
                   }
