Void and clrscr

[systemerror]

I am confused with this code, I got this tutorial from internet.

I dont understand how to use void, and the compiler say that clrscr is not declared on variable. Whats wrong?

Thanks

  #include <iostream>
#include <cstdio>
#include <conio.h>

void main()
{
    clrscr();
    cout << "Hello world \n";

    getch();
}

The problem with a lot of 'tutorials from internet' is that they are crap.

If that is an example of code from the tutorial, find another.

www.learncpp.com is also good

That code looks like it was written for an ancient version of the Borland compiler.
void main() is simply not valid code.
The other functions and <conio.h> are non-standard and may or may not exist for a given compiler.

To add to what Chervil said: why not just print a lot of '\n's to the console and reset the cursor?
