Working through "Beginning Programming"
Trying to compile very first C++ file.
The file is saved as template.cpp to D:\ root.

// C++ code template
#include <iostream.h>
void main()
    {
        // code goes here
    }

When I run it I get this message:
Error E2209 d:\template.cpp 2: Unable to open include file iostream.h
*** 1 errors in Compile ***

The file iostream.h does exist in the Include folder.

Help! And thanks in advance.
