Arrays and std :: vectors (and, presumably, all standard containers) are available for viewing in the Visual Studio debugger (you can hover over them and check their contents).
Is there a way to prepare a custom container class to allow viewing of internal data just like std :: vector?
Try to see the file %VSINSTALLDIR%\Common7\Packages\Debugger\autoexp.dat. There is a custom description of extension rules for different data types.
