but as you can see from the previous post containing the whole program the fill_account is actually fillinng the file+ the account_write functions so what should i do to delete this program (read and write works but not delete)

tabstop

I would recommend not deleting the file with all your records in it before you try to read them in.

All the w modes immediately delete the file, if it already exists. So don't use a w mode.

overlord21

only for the delete? i just use a "w" or "r" operator?

tabstop

Since the only thing you do in this function is read, you would use "rb".

overlord21

well i noticed that this function empty all the file but what i would like to is to is deleting one chosen account by making modification in t[i] and then copy the changes to the file(fwrite maybe)?

overlord21

please can anyone provide a little program using stacks (push & pop)? and another for postfix notation

tabstop

Is there a good reason why we should? Why do you expect we can do any better than the hundreds that are already on the web?

And why tack this on to the end of this thread?

overlord21

i'm so sorry i am just beginner and thought " well you can learn from more expert people if you can interact with them" but well your answer shows the opposite

just thought writing this last post would attract someone to respond instead of creating a new thread

If you know the people on this forum who are like me well (which you clearly do not) you would know me, matsp, and tabstop make mad dashes to be the first to reply to an unanswered question. Which is why the three of us so frequently give such highly redundant answers. By changing the topic around all you do is disrupt the flow of answers to the original poster's question. Which is not very fair to the original poster, now is it?

tabstop

Why would you think someone would say "oh here's post 47 about sequential files, maybe it will be about postfix notation" instead of "oh here's post 47 about sequential files, isn't that topic done already?"

And as you could have learned from this very thread, the more work you show going into the question, the more work we show going into the answer.

So if you want to know something about postfix notation, or stacks, then create a new thread -- WITH actual questions, not "why won't anybody give me teh cod3z for a stack?"

Heh... its as if all the hostile remarks I fought off saying flowed through the internet into tabstop's finger tips and made his remarks extra cutting. I like it

I can take on either side of good cop, bad cop; but bad cop is more fun
