This was my first semester project, not good enough but atleast I tried ;) 8)
In this program, user inputs a 13 digit CNIC and his gender, both are stored in a file and user castes vote, after the program terminates, a final result is also stored in a file, if previously entered CNIC is entered again the program rejects it and if user enters previously entered CNIC twice the program beeps and terminates.

First, for a C++ project, you are using alot of C-style headers. Drop the .h extension, the headers should work just fine. Most of what is in stdio.h should be already in iostream. My compiler has no iostream.h file. You sure need a fine lining between C and C++.
Secondly, your indetation here suck, hence it is alittle difficult to follow your code but lets see what good we can make of it.
For zeus' sake drop the use of goto. Just not a good programming style lately.
You better think of a better datastructure to store your cnic data.
You are clearing the screen like 100 times, not something amazing.
I also think you should read up on the good use of semaphores in loops.
I personally never thought of any use of the sound thingamajig.
Alot to improve on this code, and i presume you haven't covered classes yet but a class could have beautified things in the main function a bit.
Ooh, you also missed afew braces, fix that and more will be added. Also arrange you coe in a meaningfull manner. Here everything is like just remembered and thrown in there.

well thank you for the tips :) I'll keep those in mind.
As for .h ext I was using turboc compiler. (restriction by university)

This ^
Dude whats wrong with the <Enter> spam while you are coding.
Stop putting 1000 empty lines for each line you write, one empty line is just fine I guess(or mostly two if "needed").

I'll try not to repeat old mistakes :) as for this code, i had alot of pressure as there wasn't any time left to submit it, but then again, lame excuses are not tolerable.

Oh my god - you need to work on your coding style more than anything, bro. Indentation sucks, extra spaces suck, formatting sucks as well.

I will :)

I'm surprised that nobody mentioned anything about the use of the gets() function:
gets(cnic);
Never use gets(), ever. Sweet jesus buffer-overflow christ..

Correct.
fgets(cnic, 12, stdin);
Would be better.
