there are 3 main steps, my problem is in 1.Employee Management. And I'm still working on 2. Print Pay Slip, 3.Print Pay Report.

sorry for my poor English!

I'm Using TurboC Compiler

Why is the username and password integer datatypes ?
Why have you used cprintf ?
Syntax of fwrite is wrong

Usually, I'd tell you fflush(stdin) is wrong. But since you are using a thirty year old compiler with functions that haven't existed since the mid-80's, I'll let it go this time. I hope you aren't learning on this compiler for a potential career. You will have to unlearn a great deal. cprintf() is the Turbo graphics version of printf()

commented: Wow, you made it through nearly 1K lines of TurboCrap +19

Thank you Guys!

fflush(stdin) is from output buffers, forces all data in the buffer to be written. that's why i still using. and my institute request to use CTurbo to finish this Project. im still stacked by same problem. please i hope you guys will help me :)

Since when is stdin an output buffer? Where does it write to?

Sounds like you need to find an institute that will teach you programming... Real programming. Things have changed in the pas 30 years.
