I have tried to implement your suggestions and here is the code. No luck. I have no idea what's going on now. Thx for the help.Originally posted by Hammer

See here... in function add_record() yuo have declared dta_file as a FILE * variable, then the first time it's used in the fprintf when you try and write to it. You need to open a file with dta_file first (fopen() calls like you have in main).
Also, this is wrong in your latest post:
The highlighted part doesn't do anything. You probably meant to sayCode:dta_file = fopen("client.dat", "r+b"); //opening in binary mode for read/write (dta_file == NULL);
>if (dta_file == NULL)
And this is wrong too:
>void main()
use int main(void), and given main() a return code.
And this is even wronger
>fflush(stdin);
dont do this, it's undefined behaviour.
And why do you fopen() a file, then fclose() it almost immediatetly?
