Thread: problem with text files

I have no idea why on earth anyone would ask you to do that. Even for an assignment. The logic involved is no different than that from using a string or a c-style string to output repeatedly the contents of the file.

But... it's your call. Not going to argue about that.

I have no idea why you are having this problem only when you don't run it in debug mode. But my guess is it has probably to do with the compiler you are using and some settings getting in the way *shrug*. What do I know?...

Regardless, test your fclose() against EOF to avoid the run-time error and then see if it did in fact print the contents of each file 12 times. If not try little things like flushing the stream before closing it or clearing the stream before opening it again... dunno. Just throwing things into the air and see if anything lands face up. It's the worst way to solve a problem. But if you get it right, then you will have more info as to why the error is occuring.

As for keeping a file opened and going back and forth to print its contents, read about fgetpos() and fsetpos()

And is that really the cause of the program error?

If this is for a secret project? Something like a secret weapon against the imminent alien invasion? Or maybe a global satellite hacking mechanism? Or better yet, a new secret recipe for almonds?

If it is, then don't share. Highly sensitive information should never be shared in the net.

fflush() if you insist on using the standard C IO functions (<stdio.h>), or

&flush() if you want to become slightly cooler and draw lots of friends (<iostream.h>), or

&flush() from <iostream>, to have people begging to touch you.

Glad to know it solved it.
However, I'm afraid it's kinda of a hacked solution. fclose() is supposed to flush the stream. Don't know why it was not doing it.

Your second fopen() doesn't have a check to see if the file was opened. I don't know if you've changed your code since then. Post your latest code.

You might want to look at rewind() (a C function that sets the file pointer back at the beginning of the file) or fseek() (puts the file pointer whereever you want it) or ftell() (tells you where you are in the file so you can tell fseek() where you want to go later).

Code:

while ((fscanf(fin,"%s",wordtxtfile))!=EOF)

Your test should be

Code:

while ((fscanf(fin,"%s",wordtxtfile)) == 1)

since fscanf() can return values other than EOF on error.

I have it! You're trying to access txtfile[x][11], and txtfile was declared as

Code:

txtfile[2][11]

You should be getting a segmentation fault.
