Solution 1

Hi,

Try:

C++

#include <iostream>

The file name isn't iostream.h, but iostream
And if you don't use Windows, you can't include conio.h, because conio.h is Windows-specific.

You didn't say what version of the compiler you were using, but at one point (on Windows), the file to include was "iostream.h", then a compiler change allowed either "iostream.h" or "iostream", then a second compiler update required "iostream" and disallowed "iostream.h". I don't recall the exact version changes but I believe they occurred around VS6 or thereabouts for the Visual Studio compiler.

I suspect that you have some really old source code (ie. 2002 or older), and just need to update it a bit.

Solution #1 fills in these details...
