um working on a project in which um making something like a library system
i wanna search about a book name in a file which contains all book names and when the user enters only one or 2 letters of the book name the program shows all books with entered letters then the user continue and the number of results decreases until he finds the wanted book (prog. language : C++)
(i hope that someone understands me because i cant express well in English)
can anyone help please

 

How is this library file organized?

What OS are you using?

 

sorry what do u mean ?
the book names are listed in a file (file.txt)
if u mean operating system with OS the answer is windows.. vista
if u mean another thing plz tell me

 

Seems to me you are designing some kind of database-system. What information about a book are you going to register, and how are you going to index that information?

Is it going to be lots of books or just >100?

How is this textfile going to be organized?

Lots of things to consider when you are designing this kind of system.

 

Sounds like a sorting algorithm. I think most of us have done them while learning C.

Google sorting algorithm, should be plenty of code floating around.

 

nerdegutta=> 1.the information are book name,writer,subject
and i wanna make the user search either by name or by writer or by subject
2.no lots of books i will not make a full system it is part of the project
3.about organizing the books as i said they r all written in atext file
is this right or should we write them in an array?
um still abeginner and i need an urgent help
shteii01=> thanks for trying to help but please can u explain more ?

 

How is the text file organized? Meaning how do you separate one book from the other?

Is the text file organized like this?

bookTitle, bookAuthor, bookSubject

Or like this?

bookTitle
bookAuthor
bookSubject

Or like this?

bookTitle, bookAuthor, bookSubject, bookTitle, bookAuthor, booSubject.... and so on

I think I would make the program read the text file into an array and let the array sort the file.

The I guess it would be easy to search for titles, authors or subjects.

 

like the first code u wrote
bookTitle, bookAuthor, bookSubject
bookTitle, bookAuthor, bookSubject
.......

 

OK, then you need to make a function that reads the file, line by line, putting the fields in an array. Separated with a comma-sign(,).

When the function reaches the EOF-mark, it goes out of the loop, and into a sorting algorithm.

You now have a sorted array of the bookLib.txt file.

How is the GUI? One search-field?

 

thanks alot, i understand
about the GUI we will use the QT creator
about the "One search-field" i dont know what do u mean ??

 

Have you thought of how to present the sorted data?

Is the screen/window divided in two, upper half containing the search field, and the lower showing a list of books that matches the search field?

 

actually no,but it seems a good idea
but how to make it ?

 

What do you actually have so far, mister?

 

as i said um still a beginner
anyway thanks,mister

 

You are welcome, mister

Anytime
