Include File

I wrote a program for conversion of Kilometers into meters and Centimeters. I have given that
#include<stdio.h>
#include<conio.h>
The system in my institution gives the right output. The same program given in my system it says that -UNABLE TO OPEN INCLUDE FILE STDIO.H- and -UNABLE TO OPEN INCLUDE FILE CONIO.H-

Compile and run a "hello world" program to make sure you've properly installed the compiler. If you run into problems doing that, then it's probably your installation. We cannot offer tech support for your compiler. Get your instructor's help instead.

conio is a non-standard header. What are you compiling with that's not working?
