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()

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?

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 :)

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

can not get the float data
