# Answer to Question #27280 in C++ for Michael O' Callaghan

Question #27280
In C++ ,using Borland, how can you extract data such as Account Number, Name and Balance, from a text file? Then edit that data and save it back to the file? There are several lines of data in the file, so how do you find and edit the one you want?
First of all you must set attributes of lines, todetermine what line it is. It can be done in many ways, but two of them ispretty easy.1. Ini files. http://en.wikipedia.org/wiki/INI_file       Entry offile will be like                some_info...                Account=1247676745                Number=1558345                Name=John                More_info...2. xml files       Entry:                <params>                               <Account>                                               128676346                               </Account>                               <Number >                                               1558345                               </Number >                               <Name >                                               John                               </Name >                               Someother data                </params> To parse and edit such file you can opn them with readand write mode(http://www.cplusplus.com/doc/tutorial/files/)using ios::in | ios::out mode.Or use this thing for c++http://www.codeproject.com/Articles/17353/XML-Application-Profile-Class
