a text file generated through c++ to be well understable

Question

See more:

I made a program in c++ for courier billing/ invoice generation

The program takes the details from the user.
Saves the details in a file.
the details can be displayed again in an organized manner

The problem is that I want the file in which the details are being saved to the details exactly as they are being displayed again.
So the file can be used for printing

Thanks

And your problem is what exactly? What do you mean that it's text but not readable?

Blackdragon_adi 19-Aug-12 12:45pm

I meant that the contents of the text file are not in a proper manner

[no name] 19-Aug-12 12:47pm

That means absolutely nothing to anyone but you. What is the "proper manner" and how is your file not in the "proper manner"? We cannot see your code, your project or read your mind.

Richard MacCutchan 19-Aug-12 11:56am

Write another program that can read the file and create the invoices; that's what most people would do.

Blackdragon_adi 19-Aug-12 12:46pm

the text file has to printed as a bill

Richard MacCutchan 19-Aug-12 12:47pm

OK, so sharpen up your pencil and get coding.

JackDingler 20-Aug-12 11:00am

Richard is right. You should save the data in a generic form that's easy for your program to read.

Then write a program that reads that data and produces the report.

After all, a real world project won't stop at one report. You'll need a customer report, and internal report, perhaps a sales report...

Say for instance, you end up having to write six very different reports for the same data, what format would you choose?

Wow - that has to be the most illegible question, ever. If you wrote the program, then the output is under your control. If you want the output to look different, change your code. If you have a specific question, post the code and explain specifically what's wrong and why you're stuck.

I have posted the code

Christian Graus 19-Aug-12 20:27pm

Well, two of your case statements do nothing, and one does next to nothing. fstream.h is not valid C++, you need to include fstream ( no .h ). That's a huge block of code. However, there's no reason I can see why you can't use tabs as a delimiter, which means you can have a file that is printable, as well as being readable from your code.

Blackdragon_adi 20-Aug-12 0:27am

In the file it is not coming in a readable form like in the program

Joan M · Answer 2 · 2012-08-19T09:03:00

I don't know if this is your problem or not, but here I'm pasting you a link were it explains the ways files can be used:

http://www.cplusplus.com/reference/clibrary/cstdio/fopen/[^]

you can create the file in different methods, and if you want to create it in a way in which you can use notepad (as an example) to read it then you must use text mode. if you serialize a complete structure in binary mode then you won't be able to read it easily.

Take a look at this link and improve your question if you need further help.

Good luck.
