It won't compile. There is no such header file as conio.h. There
is no such routine as clrscr(). main returns an int, not void. I
did not look further.
At least in C. If you are using some other language with vague
similarities to C you need to use a newsgroup that deals with that
language. This is not it.
As I'm sure you know, there is a header file called conio.h and a
function called clrscr() *on some systems*. (Of course, there's no
reason to use either in a program that just performs some mathematical
operations.)
Declaring "void main()" makes it incorrect C, not non-C.
The use of system-specific headers and functions makes the program
non-portable (and off-topic here); it doesn't make it non-C. One of
C's greatest assets is its ability to support system-specific
extensions.
What makes the program non-C is its use of "Else" and "If" rather than
"else" and "if".

We must do something. This is something. Therefore, we must do this.
