                    Hello there,i am doing programming in c== using files.But when i am writing some record in file through class objects they r written properly but on printing the rec i am getting some strange characters or other numbers that i have not written in file.Sometimes the record r read & displayed properly but the last rec is displayed twice?Why it's happening?Pleas e help

                      i have also used ifstream & ofstream.But in case of modification we have to write the new rec in position where the old rec was.That's why before reading every rec its position in file(using tellg())in terms of byteno is taken & then file pointer is moved at that byte no(using seekg()) & the rec is written in file using write fun.That's what the logic is I don't understand what's wrong in it.In book also the program is written like this?If...

                        I have aproblem in selection sort.Why we store minimum int value(int_min)i n
                        0 th positin.What's the use?
                        In stead of dsoing this if we consider the actual 1st element as smallest then also we can follow the method then why int_min is used in c++?
                        Please Help.

                            The code is for modyfying a record in an existing file
                            So i have taken emp id from user & then that id is searched in a file.If it matches with the id of any re in file whole rec is modified.But when i wrote loop for traversing throug rec in file it shows rec not found.I traced my program n i found that it doesn't go inside the loop even if rec are present in file
                            I hope my question is clear now n i will get solution for it....

                                      hi,
                                      I checked my code.It's correct,I have taken it from a book.
                                      the point of confusion for me is that,
                                      pointer var always stores addresses.
                                      so when we write,
                                      int *ptr;
                                      int i=10;ptr=&i;
                                      then if we write,
                                      cout<<ptr
                                      we get address of int i stored in ptr.
                                      but in case of char
                                      like

                                      char *ptr;
                                      char c='a'
                                      ...

                                        but it gives the addr of pointer & not the addr of te var to which it points.
                                        Where the addr is stored?
                                        as we initialises pointer with the addr.

                                          Why 'this' pointer is used?As we always call function with object name so fun knows which objects's values r to be used? What's d exact use of this pointer?
                                          If possible explain with code.
