Source files are normally simple text files. I assume StrongEd has
some means of identifying them. I use Zap, and one way that guesses
the filetype is to look whether the file is in a directory of c, h,
s, etc.

You can place the sources and compiler output wherever you want. The 
harddisc root is clearly not a good place, but I would not store 
anything where !GCC is either. Best to have !GCC somewhere on its own 
and your programming projects somewhere on their own.

All you need to do is to set the current directory before compiling. 
The easiest way to do that is to have an Obey file (or even better, a 
TaskObey file) in the directory containing your project, i.e., the 
directory containing the "h", "c", "cpp" and "o" sub-directories. That 
Obey file then sets the directory and starts compilation.

Dir <Obey$Dir>
... all the other commands for compiling

All names you pass to !GCC are treated as relative to the current 
directory.

I use Sams Teach Yourself C++ in 21 days. (Been using it for years!)

#include <iostream>

int main(void)
{
    using namespace std;
    cout << "Hello World\n" << endl;
    return 0;
}

Well, that should give a clue. Without the iostream header file the 
following code cannot compile. Looks like you have not installed GCC 
correctly. This works fine here with GCC 4.1.1.

> test.cpp:3: error: '::main' must return 'int'

The above is not correct C++. The standard requires 'main' to return 
an 'int' value.

Take 2, the command to compile C++ is g++.

The source file 'test' shound be in a subdirectory called 'cpp'.
