Need help Regarding Bank System Project!

hi
i need urgent help if somebody can do for it


below is the code

the problem is that my search function not working , it always show the last value correct but not the first and others

Code:

So in the last couple of hours, you've basically ignored everything suggested so far and decided to one again try the begging approach.

http://cboard.cprogramming.com/c-pro...data-file.html

I'm done caring about you.

Seriously... I don't know anyone who is going to sift through 728 lines of code to fix your problem... especially when it uses gets(), itoa(), strcmpi(), etc.

Tried to compile after a rewrite and run, works fine, until it crashes with a seg fault.
