I would like read some of the "include" source files but where can I find them? In what directory are they normally stored? I'm using Microsoft Visual Studio 2008 Express version with Windows Vista (32bit). Thanks.
In VC++ IDE the easiest thing is right clicking on the header name (in the line you #included it) and select Open Document <header name>.
However the C++ core headers should have a path like this:
C:\Program Files\Microsoft Visual Studio 9.0\VC\include
