Can Someone Help Me Find Error in This Program?

<edit>OP deleted their post and ran away.

USAFrenzy rescued the mess and it's posted below in message https://www.cplusplus.com/forum/general/281826/#msg1219577

Well you could make it so it's easier to read.
https://www.cplusplus.com/articles/jEywvCM9/

Then decide whether you're using C or C++.

> gets(buffer);
Then throw away your obsolete books / tutors / compilers which still permit this nonsense.

[seeplus]

can someone help me?

With what? Does the code compile? If yes, then what debugging of the code have you done? Where does tracing through the code with the debugger deviate from that expected from your program design?

What compiler are you using? gotoxy(), clrscr() etc are from an ancient version of Borland Turbo C++ and aren't supported with modern C++ compilers.

gets() was depreciated in C++11 and removed in C++14.

As mentioned by salam above, If you're coding in C++ then use C++, if you're using c then code in c. Don't mix and max...

[kbw]

conio.h with gotoxy() calls, looks like an old Borland 3.x program written as C with the C++ iostream library.

You have to tell us what the problem is. We won't just look for bugs in your code.

Every time I see this I think something like
"I am conio! I need VI for my bunghole! "
I think something even less polite if my code catches a uniSTD

NOT ANSWERING OP's QUESTION, but I am reformatting their code for readability

With that said - no version of C++ lets this compile from C++11 on... (only tried very briefly with modern c++), there are a bunch of issues at a glance (like random NULLS all throughout with fopens and the very top struct being an issue as well - this reported 75 errors as is)
Hopefully OP gets back to what their issue is here and someone can help them out

You haven't formatted it correctly, the switch in main() is still a mess for example.

The code has lots of syntax errors, maybe that's the error the OP meant. At any rate, he/she's shown little interest since posting, so it may not be worth fixing them.

[USAFrenzy]

ah crap, my bad on that one - just was quickly reformatting OP's post for some readability but you're correct

I'm impressed that you found it.

Now that there's some context, it may be worth fixing ...

EDIT: Now that I'm looking at the code, it looks like it was typed in by an office typist and never checked.

[mbozzi]

I'm impressed that you found it.

Thanks. I chose a distinctive looking program fragment, like
5.Aplikasi/testing jaringan
double-quoted it, and fed the result to Google.
