What is the problem with the delay function. compiler is giving Error on that inappropriate call of delay function.

What is the problem with this code.

1) Using deprecated header names.
2) Using non-standard libraries (conio.h, dos.h). Wow, DOS.
3) Writing void main() instead of int main() which is the standard.

As for your post, you did not use code tags. You could edit your original post and put your code into code tags right now.

It is difficult to help you. You shouldn't just throw the source code at us and ask "what's wrong with it?"

Instead you must tell us what compiler errors you get, what you want the code to do and it doesn't do, and so on.

And always post a short post, trying to keep the code you post to a minimum so that we can focus on solving the problem instead of searching for it.
