Thread: file

I'm trying to append a txt file which I created by using C program.
I manually wrote some information into that txt file and now it has 5 filled up information. This file can hold up to 20 information. Which tells us that we only can store 15 more information.
I've tried using a+ and checked for NULL condition in my file. However, none of these worked. I'm sure 6 to 20 elements are NULL, because the file only has 5 information so far.
Could anyone help me with appending a txt file?

Sure Toshiro.

Post up your code so we can see where the problem is. My "remote viewing" supersensors, are in the repair shop.

Why do you think that the file can only take "20 information" (assuming you mean objects/records/elements/...)?

Anyways, show your code.

Bye, Andreas

I think I fixed it by myself....

Unless your hard disk is filled up, don't you think it should be able to store more than that?

So, did fopen return a null pointer or not?

I'm sure 6 to 20 elements are NULL, because the file only has 5 information so far.

What does this mean?

Even though it won't 'fix' your program, "a+" opens the file, in append mode, for writing *and* reading (update). Since you're only writing to it, you want "a".
