Dear everybody,
kindly please help me out with this problem.
and i'm thinking to add in few commands for my program in order to make it able to save the input from user, but i have no idea where or which line to insert it, any help would be appreciated.
thank you so so much.
first u have to learn--"how to write code in readable format".
i don't have any desire to see that any more.
thanx...
>in order to make it able to save the input from user
You mean 'ask' it to save input from the user. Programs are living organisms that hate you, you have to be nice.
By save input, what exactly do you mean? You are already saving the user input to memory when you place it in variables. Where else do you want to save it?
>first u have to learn--"how to write code in readable format".
Wha? I didn't see any real problem with the formatting of the code.
-Prelude
I got lost somewhere around
if (a==1)
Invoice_Func();
What ever happend to making all function call from withing the main function?
I'm trying to save the input from user into .txt or .dat format.
something similiar to the attachement.
i'm trying to copy and paste it to my program, but i have no idea how, as you can see, that i'm new to this and not good in programming, that's wy my program is a mess.
any comment is appreciated. thank you very much.
i've made some changes to the program, but still it's a mess, kindly please ignore the previous one. thank you.
Write a binary mode file to disk that contains the contents of an array that holds all of the user input.
Declare a pointer to a type FILE structure, and use the fwrite() function.
When you run the program again, use the fread() function to read back into the array the previous user input.
Search through the STDIO.H file, to see all of the function prototypes that you can pass a pointer to a FILE structure, there are many more.
One very good book that will teach you how to use these functions, is Sams Teach Yourself C in 21 Days.
I don't know if this is exactly what you are wanting, but the source file below should compile and link to an executable. When you run the program it will write a text file to the Windows Desktop and open it automatically in NOTEPAD (assuming you are using a Win9x OS).
This should be enough to give you a jump start in saving program I/O to disk.
Other programmers on this site can do far better than what I have done here, so this is certainly not the best way to save information.
Hi there,
Well i couldn't make much out of your code, however i understand you want to invoice furniture and save the invoices on a file on disk. The following code should get you started. It tests for a file called "furnish" on your hard drive and if it doesn't find it it creates it, this is the data file for your program, the rest of the code just write details of the invoice to the disk.
I will need to leave it to you to write the code to read the file back to screen, however i have included code to repeat the variables back onto the screen as you type. You can use code based on my code to read the file back into memory and then review and format and print the invoices.
Ok if you get any more probs you can post again, the program is not fully error checked so don't enter illegal keys, or it might hang. If you make alterations to the code it is a good idea to delete the data file from the hard disk and allow the program to recreate it. So don't enter too much test data between alterations or you will have to put it back in again.
