ALl the 2 ABove are the code pls help me to understand the process Thanks
jonnin (11444)
option F appears to delete an entry from the file.
It does this by rewriting the file without the offending data and swapping the new file over the old one.

this code has a lot of issues... gotos, system exit (closes the terminal, but not the program, I think?), plaintext login visible in the compiled code, monolith, and more. It looks like someone who know what they were doing (sort of) got in a hurry and hacked this out to 'get it done' . I would just rewrite it rather than try to fix or understand it. Understanding it, its a bad example of doing things.

As jonin mentioned, you have lots of problems.

A few that jump out:
Line 31: You should do a return 0; here. Then there would be no need to put the rest of the program under an if statement at line 34.

You program should be broken into functions. One function for each branch of your switch statement.

Line 77: You're outputting multiple fields to appointmentlist.txt.
Line 309: When you checking to delete, you're not checking just the name, you're checking against the whole record that was written at line 77. Not user friendly.

Line 301: Why are you opening seek2? Your don't use it.

                cout << endl << " Go back to main menu? (Y/N): ";
                cin >> home;
                if (home == 'y' || home == 'Y')
                    {
                        goto start;
                    }
                else if (home == 'N' || home == 'n')
                {
                    system("exit");
                }
                else
                {
                    goto start;
                }

This code is just bad.

It is repeated in every branch of your switch statement. It should appear only once AFTER the switch statement.

You should avoid gotos.

If you want to terminate the program, just return 0 from main or call exit(0);
system("exit") will exit your system shell.

there is a part at the reservation


look like this getline(myfile,strOutput,'|")

what does '|' mean??
AbstractionAnon (6954)
Have you read the documentation for getline?
http://www.cplusplus.com/reference/string/string/getline/?kw=getline

'|' is a delimiter.

istream& getline (istream& is, string& str, char delim);
